I'm just not a big fan of instrumental solos, but especially unaccompanied ones. Plus something which is rhythmic rather than melodic - e.g. drums - is rarely going to hold my interest. The first time there's a 'WTFSKILL' factor, but the second time it's like, well, you're just bashing at 'em for ten minutes, aren'tcha.
If you can fit a drum solo so that it's awesome within the context of the music - say, the breakdown drumming in 'Won't Get Fooled Again' - then that's a different story. I hate Led Zep's live stuff usually anyway. They masturbate for hooooouuurs.
