The waiting is gonna be the hardest part for Tom Petty fans eager to discover the riches of "An American Treasure," the Rock and Roll Hall of Famer's first posthumous album.
The career-spanning four-CD box set—which won't be available until September 28, more than two months from now—will feature 60 previously unreleased tracks, including live cuts and alternate versions of some of Petty's greatest hits.
A two-CD option will also be released.
"An American Treasure" was amassed by Petty's wife, Dana, his daughter, Adria, and two members of his longtime backing band, the Heartbreakers: guitarist Mike Campbell and keyboard player Benmont Tench.
Tom Petty and the Heartbreakers celebrated their 40th anniversary last year with an extensive tour. On October 2, one week after the final show, he collapsed after an accidental overdose of prescription painkillers at his home in Malibu, California, and later died at a nearby hospital. He was 66.
