The 25th anniversary of Nirvana's "Nevermind" is such a big deal in Dad Rock Nation that we had to split the episode into two parts.

Jim and Patrick go track-by-track on this landscape-shifting album, with some listener comments and a few words from producer Butch Vig.

Check back Friday, Sept. 23 for "side two."
