I haven't listened to this podcast, but Season 2 focuses on The Smashing Pumpkins.
Each episode discusses an album review, with 6 so far starting at Gish and so far up to Machina. Each is at least 2 hours long, so that's 12 hours or more of listening pleasure. Maybe.
Some of you may find it interesting.
