American Treasure, a four-CD box set of unreleased music from the Tom Petty vaults, is coming September 28th.
The 60-song, career-spanning collection will feature previously unissued recordings, both studio and live.
Petty’s daughter Adria, his wife Dana, and original Heartbreakers Mike Campbell and Benmont Tench all had a hand in compiling it. .
What we know about it so far was announced Tuesday on the SiriusXM Petty channel, which also previewed a 1982 song from it, "Keep a Little Soul."
More details are expected tomorrow (Wednesday) morning, the setting for a countdown clock that began on Petty’s website earlier this week.
