Verve went downhill real fast didn't they, though I personally think they're worth listening to up until some of the tracks on Urban Hymns.
I think it was when someone had the idea to turn up Ashcroft's vocals that it went to shit, their debut album and then EP were beautiful with his voice swirling around McCabe's spacey guitar parts.
Moreso I would say that with Ashcroft dominating the reformed Verve McCabe(and indeed Jones) was side lined, stuff like The Rolling People predates there first spilt if I remember correctly although it would probably have been a lot better recorded back then without Ashcrofts vocals dominating.
Keeping things in somewhat similar musical territory I always liked the bootleg recording of the last date of Floyds 1977 in Montreal. Its the show were Waters gets pissed off at the unruly audience and spits on a fan supposedly inspiring The Wall. Whilst many(me included) would argue that inspiring that album isn't a positive attribute the Montreal show itself is excellent in the sense of pissed of angst from an otherwise somewhat too comfortable Floyd.
Waters gets pissed at the Fan during one of the parts of Pigs on the Wing but actually spits on him during Pigs(three different kinds) at the end of the first set. Already a performance with a bit more edge on it the spitting happens about 17 mins in during the outro and Waters bring the fan in close to do it actually puts a nice little act calling the fan out like a dog.

Part 8 with Gilmour and Snowey White trading brutal guitar lines is probably the best soloing I'v heard from Floyd...
