A box set featuring 60 previously unreleased tracks by Tom Petty And The Heartbreakers will arrive later this year.
The 4CD collection is titled An American Treasure and will arrive on September 28, along with a 2CD version.
SiriusXM report (via Rolling Stone) that the album will feature studio recordings, live material and alternative versions of some of Petty’s best-loved work.
It was compiled by Petty’s widow Dana and his daughter Adria, along with Heartbreakers’ keyboardist Belmont Trench, guitarist Mike Campbell and longtime collaborator Ryan Ulyate.
Further details on An American Treasure will be revealed in due course.
Petty died in October last year at the age of 66, with a medical examiner reporting that he died of an accidental drug overdose.
Petty’s family reported that on the day he died, he’d been told that his hip fracture had become a full break and it was their feeling that “the pain was simply unbearable and was the cause for his over use of medication.”
Petty’s final studio album with the Heartbreakers was 2014’s Hypnotic Eye.
