I know we are talking about guitar solos here, but in order to hear the solo, you have to be able to stand the rest of the song, which is probably why I am not familiar with the solo on the last song of division bell. I just hate that album. Compare the overall sound of Ummagumma to that of Division Bell. Division Bell sounds like elevator music imo.
On a more topical note, its all a matter of taste, and some people find their sense of utter bliss in complex solos with odd time signatures.
( Still Ron Jarzombek ftw)
