Late Foo Fighters drummer Taylor Hawkins is being saluted with two all-star tribute concerts in September -- and Miley Cyrus and Alanis Morissette are on the bill for one of them.

Cyrus and Morissette are among the many stars who'll be performing at The Kia Forum in Los Angeles on Sept. 27.

Mark Ronson is also on the bill, as are Joan Jett and members of KISS, Queen, The Police, Rush and the Red Hot Chili Peppers.

The concept of the show is that Hawkins' "bandmates and his inspirations" will be "playing the songs that he fell in love with, and the ones he brought to life."

So where do Cyrus and Morissette fit in? Well, from 1995 to 1997, before Hawkins joined Foo Fighters, he was Morissette's drummer on her tour supporting her album "Jagged Little Pill." He also appeared in her videos for "You Oughta Know," "All I Really Want" and "You Learn."

As for Cyrus, she and Hawkins were friends; he played on her 2021 album "Plastic Hearts." She and Foo Fighters headlined the Lollapalooza Chile festival on March 18 and 19. After Hawkins died on March 25, she filled in for Foo Fighters at Lollapalooza Brazil and dedicated her show to him.

Another concert with some of the same performers will take place Sept. 3 at London's Wembley Stadium.

Tickets to both shows go on sale June 17 at 9 a.m. local time. Proceeds will benefit charities in the U.K. and U.S. chosen by the Hawkins family.

Hawkins died March 25 when the band was on tour in Colombia. No cause of death was announced at the time. Colombian authorities announced the drummer had 10 substances in his system at the time of his death, including opioids, antidepressants and THC.
