So I don't know if you guys have seen the "Classic Album" series, but they've finally (its about damn time) released one for Tom Petty - http://bit.ly/cyHzQq.
You get a bunch of unreleased tracks that didn't make it on Damn the torpedoes and some live performance footage. Ok but the best part? You feel like youre in the band while youre literally watching the Tom petty / producer jimmy iovine at the mixing board, picking out certain sounds, licks, and creating the tracks.
