The late Tom Petty's treasure trove of material is a lot deeper than it seemed. Last year saw the release of An American Treasure, a 60-track box set with tons of rare and unreleased early songs. This new box set entitled The Best Of Everything is considered to be a supplement to that one.
In this article from UCR, the Geffen Records/UMe press release states:
"Rather than chronological order, the special cross-label collection was sequenced as a hard-hitting playlist giving the entire catalog equal prominence. Included are songs from his solo projects, songs with world-class musicians the Heartbreakers, as well as essentials from the reformed Mudcrutch."
The new set will be available March 1st in digital format, 2-disc or 4LP-black and clear-colored vinyl. More details HERE
