I've enjoyed some extended-length rock tracks, like the above-mentioned Echoes. Close To The Edge by Yes comes to mind as well. But In-A-Gadda is a bit too much for me. Is the the studio cut or a live version I believe I once heard that has a drum solo in the middle? I always thought drum solos suck anyway and that one in particular literally defines the word interminable...
