Another Tom Petty Box Set In The Works

The new Tom Petty box set An American Treasure won't be out until later this month, but Heartbreakers guitarist Mike Campbell says group is already planning for the next one.

Campbell says he wants to do a box set the band's legendary 1997 residency at San Francisco's Fillmore, which he calls "almost the pinnacle of the band just being totally spontaneous".

Campbell says he would imagine Petty was sitting next to him in the studio while picking out material for An American Treasure.
