I've never been to these BBC production shows, except for Smashing Pumpkins two years ago that I went to, but I always wonder how bands actually sound like when they play to the tracks. I find it funny when the crash goes when its not hit (EDIT: Referring to the Jam in the studio performance). I remembered Nirvana made a joke of it in Top of the Pops. I don't think it happens now though with better live tracking technology.
I guess Teen Spirit has a nice bass line. Some more bass lines to mention
Sam RIvers:
Justin Chancellor:
And the legend MCA Adam Yauch
Motorhead has killer bass but technically they are more guitar than bass the way Lemmy plays them
