It was a 20 night stand at the Fillmore in San Francisco in 1997. As Mike Campbell, guitarist for Petty, describes it the band was free not to play the same set list every night and jam. Jam they did on the last night Feb.7th. That show lasted for 3 hours and 40 minutes. Mike says "nothing would ever top the length and excitement of that" . Now all those shows have been mixed and being released in a boxset. Stay tuned for a release date of what's sure to be an incredible collection of songs and to relive some of the most exciting nights in a 40 year career of Tom Petty and the Heartbreakers. https://ultimateclassicrock.com/tom-petty-fillmore-box-set-2022/
