Michael Mosbach, the longtime security chief and motorcycle riding partner of late Rush drummer Neil Peart, has died of glioblastoma, the same form of brain cancer that killed Peart in 2020.

Known to Rush fans as “Praetorian,” Mosbach joined the band’s circle in the early 2000s and became a trusted friend to Peart, accompanying him on motorcycle trips between tour stops. His relationship with the drummer extended well beyond their professional bond, with the pair sharing years of travel and conversations on the road, some of which found their way into Peart's books and essays.

After Peart’s death, Mosbach helped carry on his friend’s legacy through the Bubba Bash, a benefit concert launched in 2023 to raise money for glioblastoma research at Cedars-Sinai in Los Angeles. The event brings together musicians to perform in tribute to Peart, whose nickname inspired its name.

RUSH confirmed Mosbach’s death in a statement shared with fans.

“As many Rush fans know, Michael Mosbach was Neil’s longtime security and riding partner on tour for decades. Through thick and thin, he was always there for Neil, and for that we are eternally grateful.

We are saddened to now share that he has passed after his own cancer battle.

Our sincere condolences to his family & friends, and our greater Rush family that worked with him over the years. RIP Michael”

The news also prompted tributes from members of the Rush community, including RushCon, which remembered Mosbach for his loyalty, generosity and continued work honouring Peart through the annual benefit.

Peart died on January 7, 2020, after a private battle with glioblastoma. He was 67.

Slayyyter in "I Think He's Got a Girl" video.

It looks like Slayyyter’s Wor$t Man in America is a cheater, as the musician conveys in the accompanying video for the upcoming album’s latest single, “I Think He’s Got a Girl.”

In her self-directed new visual for the ballad, Slayyyter is seen in a luxe home, appearing in an array of vintage outfits, striking gorgeous pinup poses, all alone. From lounging in the pool, to barbecuing and hanging out in different rooms, she laments a relationship that’s unraveling as she comes to the realization that the object of her affection has moved on with another.

“You’re too quick on the draw, lie every time you talk/It makes me feel so crazy, like I got everything wrong,” she sings. “You’re quiet on the phone, what time you coming home?/I hope it doesn’t mean what I know it means” before coming to the realization on the belted chorus: “I think he’s got a girl.”

The counterpart album to Wor$t Girl in America, Wor$t Man in America arrives on Dec. 4 via Columbia, and includes nine tracks. In addition to “I Think He’s Got a Girl,” which appears to be the inverse of Wor$t Girl’s “Unknown Loverz,” she’s also already released LP tracks “Crank 2” and “Beat Up Chanel$,” which offered fresh takes on Wor$t Girl tracks “Crank” and “Brand New Chanel$,” respectively.

In a recent interview with Rolling Stone, Slayyyter explained the impetus for Wor$t Man in America, saying, “I want to live here for a little longer, so I’m kind of making an inverse album, if you will. I just want the core of everything to feel like me, because it finally feels that.”

Alanis Morissette is bringing an unexpected collection of collaborators to Good Weather for Immaculate Conception, her first full-length holiday album. Arriving on Nov. 6, it features Brandi Carlile, Steve Martin, Martin Short and several other guests across 14 tracks.

The Canadian singer today shared its first single, “Beautiful Star of Bethlehem,” featuring Carlile and Martin. The album's tracklist includes traditional Christmas standards, previously released covers and two original songs.

Among the other guests, Short appears on the album’s closing track, “Merry Christmas.” Joy Oladokun joins Morissette for “Silent Night,” while Amythyst Kiah contributes to “Momma Mary.” The record also features Trans Voices, the U.K.’s first professional vocal ensemble of trans and nonbinary singers, on “O Tannenbaum.”

Speaking to Alex Cooper on the Call Her Daddy podcast in September, before officially announcing the album, she described the record as “this labor of Christmas love for me.”

The release brings several of Morissette’s seasonal recordings together on one album. She has previously released “Happy Xmas (War Is Over),” her take on the John Lennon and Yoko Ono classic, in 2020, followed by “Little Drummer Boy” in 2022, “Last Christmas” in 2023 and “O Holy Night” in 2024.

Those recordings join selections including “What Child Is This?,” “Ave Maria” and Joni Mitchell’s “River” on the new album.

Argentine musician Piero sings during a show at Newell's Olds Boys Stadium on April, 1983 in Rosario, Argentina.

Piero, the artist who defined a generation of Latin American songwriting with classics like “Mi Viejo” and “Soy Pan, Soy Paz, Soy Más,” died on Oct. 7 at Hospital Italiano in Buenos Aires. He was 81.

His family confirmed the news via their Instagram account: “It is with deep sorrow that we announce the passing of our beloved Piero at the age of 81. His voice, his songs, and his message of peace will remain with us forever. His light will continue to shine in every corner where his music is heard. His family and friends thank you for your condolences. Farewell, dear Piero,” they wrote.

Piero Antonio Franco De Benedictis was born in Gallipoli, Apulia, Italy, in 1945. His family emigrated to Argentina when he was three. By the early 1970s, Piero was already a celebrity. He co-starred in the film El Profesor Patagónico alongside Luis Sandrini, directed by Fernando Ayala.

As he released albums — especially the trilogy Pedro Nadie (1970), Coplas De Mi País (1972), and Para El Pueblo Lo Que Es Del Pueblo (1974) — he became a political figure. A committed singer-songwriter who spoke out on social issues, he found an inseparable songwriting partner in José Tcherkasky, the Argentine journalist and poet.

Associated with protest songs, Piero and Tcherkasky painted social portraits and crafted short stories with universal appeal, often accompanied by the great Jorge López Ruiz orchestrations. Songs such as “Valdemar, El Brasilero” and “Los Americanos,” featuring the musical group Cuarteto Zupay, were part of that seminal repertoire that influenced, for example, the Panamanian salsa singer Rubén Blades.

Para El Pueblo Lo Que Es Del Pueblo, he collaborated with Marilina Ross (“Canción De Una Para Despertar Un Hijo”), depicted the hardships of urban life (“Así Es La Ciudad”), and covered “Te Recuerdo, Amanda” by the Chilean Víctor Jara, who was assassinated by Augusto Pinochet’s dictatorship in Chile in September of the previous year.

Following the coup d’état of March 24, he went into exile in 1976 and lived in Italy and Spain, where he settled near Madrid, and worked on a farm. He maintained strong ties to Colombia. His children’s album, Sinfonía Inconclusa En La Mar (1975), is an iconic album for several generations of Colombians.

In 1981, with the end of the civil-military dictatorship on the near horizon, Piero planned his return to Argentina, stopping in Uruguay first. Alongside musicians he’d met during his exile in Spain — including guitarists Amadeo Álvarez and Daniel Manzini — he began to shape his new band, Prema. Over the next five years, Prema’s lineup included, among others, pianist Babu Cerviño (a member of the band Tantor), drummer Juan Carlos “El Negro” Tordó (who had played in the band Raíces with Uruguayan musician Beto Satragni and a very young Andrés Calamaro), and more.

Piero reached his peak of popularity during those years. He performed in several plays and formed a deep bond with Mercedes Sosa, participating in the legendary concerts at the Ópera Theater. These popularized her cry of gratitude, “¡Gracias, Piero!” He took part in the historic concerts by Silvio Rodríguez and Pablo Milanés in Buenos Aires. In the mid-1980s, he moved away from protest music. He founded an organic farm in Campana alongside teenagers from vulnerable families. From then on, during the mid-1990s, he built a network of 200 organic farms, and his social activism went hand in hand with an artistic career that included a collaborative album with Milanés.

Music became a family legacy. His son Juan led the band Mulan and currently plays guitar for the Uruguayan singer Ana Prada. In 2022, his daughter Fiorel released an EP featuring Piero himself, with covers of classic Argentine folk songs.

Nickelback will hit arenas across Canada next year on their newly announced global tour supporting the band's upcoming album, Everything Under the Sun.

The Everything Under the Sun 2027 Tour will span North America, Europe and Australia, with British rock band Don Broco joining the Canadian group as direct support. The North American leg begins February 6 in Pittsburgh and runs through May 1 in San Antonio, Texas, before the tour moves overseas.

The Canadian dates begin March 12 at Montréal's Centre Bell, before heading to Hamilton's TD Coliseum and Toronto's Scotiabank Arena the following week. The band will return to Canada in April for concerts in Saskatoon, Edmonton, Calgary and Vancouver.

Nickelback's 11th studio album will mark the band's first full-length release since 2022's Get Rollin'. The band has released three singles so far, “Rattle the Cage,” featuring former Marilyn Manson guitarist John 5, “Leave Me Behind” and “Make Me Love You.” The Hana, Alberta band has described the record as being characterized by more experimental material and introspective songwriting.

Tickets go on sale to the general public October 16 at 10 a.m. local time, following presales beginning October 13.

Everything Under the Sun arrives October 30.
