Tom Petty & the Heartbreakers Unearth Previously Unreleased Material for New Box Set
Having reissued their studio work with a pair of box sets in 2016, Tom Petty & the Heartbreakers have dug even deeper into the vault to put together a new set of rarities.

Titled An American Treasure, the upcoming box set arrives September 28 through Reprise. The package will include previously unheard recordings, in addition to alternate versions, early takes and live recordings. It marks the first posthumous release from Petty since his passing last October.

Petty's daughter, Adria, and wife Dana served as executive producers of An American Treasure, curating the tracklist alongside Heartbreakers bandmates Mike Campbell and Benmont Tench, in addition to collaborator Ryan Ulyate. The box set's artwork was designed by Shepard Fairey.

An American Treasure will arrive in four different formats: a standard 2-CD collection, a 60-track deluxe 4-CD set with liner notes, a super deluxe 4-CD box set and a 6-LP vinyl box set. All four formats are available for pre-order here.

Adria and Dana spoke about the set in the following statement:

Everyone involved in this project chose each track with tremendous care and deep respect for the body of work Tom Petty created over the course of 40 years. He also accumulated a wealth of unreleased music in his vaults, and we have collectively uncovered one gem after another that will keep us all listening and discovering new facets of Tom's talent for many years to come. We can't wait to share with Tom's fans this musical portrait of an artist who deeply affected our culture and indelibly touched the lives of fans the world over.

Alongside the announcement of An American Treasure, the previously unheard track "Keep a Little Soul," recorded in 1982, can be heard in the player below.

Petty was found unconscious at his Malibu home on October 2, 2017. He was taken to hospital and put on life support, where he died hours later. A medical examiner ruled in January that Petty had died of an accidental drug overdose. He was 66.
