OffBeat is saddened to report that Tom Petty has died, just a few months after performing a dazzling set at Jazz Fest.

According to CBS, the 66-year-old Grammy-winning rock icon was found unconscious in his Malibu home before being rushed to an area hospital in full cardiac arrest on Sunday, October 1. The frontman of Tom Petty and the Heartbreakers was placed on life support but succumbed to the fatal heart attack on Monday, October 2.

Rising to stardom in the 1970s, Tom Petty and the Heartbreakers will be remembered for hits like “American Girl,” “Stop Draggin’ My Heart Around,” “Breakdown,” and “Listen to Her Heart.” Petty’s musicianship extended well beyond radio hits, and he remained a formidable performer well into his sixties. As OffBeat’s John Swenson wrote in May 2017, “Petty writes rockers with a two guitar bite and memorable hooks and he can line up an impressive array of those tunes. Many of this band’s peers are now relegated to self parody but Petty’s band is impressively musical and he really treated his fans to something special.” Tom and his band were inducted into the Rock and Roll Hall of Fame in 2002.

In a 2012 interview with OffBeat, Petty discussed his southern-ness, saying “I can never get rid of it. I think it really helped [the Heartbreakers]. We really did have to learn to play, to deliver. Once you got up onstage, you really gotta play, or it would be ‘Okay, that’s enough of you. We have some guys up here that work on tractors all day, but they can play like crazy.’ We were all just shitkickers then.”

OffBeat sends its condolences to the Petty family and the millions left with broken hearts.
