An American Treasure is a new career-spanning Tom Petty box set. In addition to previously unreleased tracks, the set includes live takes, alternate versions, rarities, and deep cuts from throughout his catalogue. It will be released in four versions: a deluxe and expanded “Super Deluxe” 4xCD set featuring 60 tracks and extensive liner notes; a 6xLP vinyl edition; and a standard 2xCD collection featuring 26 highlights. An American Treasure is out September 28 via Reprise. Below, watch the video for “Keep a Little Soul,” a previously unreleased track recorded in 1982.

Adria Petty—Tom’s daughter—and Dana Petty, his wife, served as executive producers for the box set. They curated the tracklist along with Petty’s Heartbreakers bandmates Mike Campbell and Benmont Tench, as well as collaborator Ryan Ulyate. The artwork was created by Shepard Fairey (illustrator and founder of OBEY Clothing).

In a statement, Adria and Dana Petty write, “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.”

Tom Petty died in October 2017 at the age of 66 from an accidental drug overdose. His last solo record was 2006’s Highway Companion. He released Hypnotic Eye with the Heartbreakers in 2014.
