Tom Petty, best known as the frontman of Tom Petty and the Heartbreakers, has died at the age of 66.

The legendary musician suffered a full cardiac arrest and was found unconscious and not breathing in his Malibu home Sunday night. He was taken to UCLA Santa Monica Hospital and put on life support, reports TMZ.

Petty rose to fame in the 1970s with The Heartbreakers, releasing hits such as “American Girl”, “Free Fallin'”, “Breakdown” and more. The band was inducted into Rock n Roll’s Hall of Fame back in in 2002.

Their first album was released in 1976 and have been performing for over four decades. Last Monday, Petty played his final three performances at Hollywood Bowl, all sold-out, concluding their 40th anniversary tour. 53 shows in 24 states was the final tally according to the band’s website.

Petty told Rolling Stone that he thought this would be the band’s last tour together:

“It’s very likely we’ll keep playing, but will we take on 50 shows in one tour? I don’t think so. I’d be lying if I didn’t say I was thinking this might be the last big one. We’re all on the backside of our sixties. I have a granddaughter now I’d like to see as much as I can. I don’t want to spend my life on the road. This tour will take me away for four months. With a little kid, that’s a lot of time.”

Petty, who released three solo albums and 13 albums with Tom Petty and the Heartbreakers, also took part in the 1980s supergroup the Traveling Wilburys with Bob Dylan, George Harrison, Roy Orbison and Jeff Lynne.
