Petty's daughter Adria made a promotional music video for the track 'Keep a Little Soul' using home movies. The goal for compiling the songs was to highlight lesser-known tracks and choose songs that Petty himself would prefer.
The recordings were chosen for remixing and remastering by Mike Campbell, Adria Petty, Dana Petty, Benmont Tench, and Ryan Ulyate. The majority of the content is Heartbreakers material but there are also several solo songs and some recordings by Mudcrutch. The set includes several rare and unreleased songs alongside more obscure album tracks that showcase Petty's songwriting.
