I have the Jimi Hendrix and Led Zeppelin BBC sessions, and they both rule. Are there any other BBC session recordings of which I and others should be aware?
Yeah, Jackolas IN SESSION!!!!!!!!!

Lots of good bands have in sessions. Therapy? and Rage Against The Machine spring to mind.
Rage has BBC session recordings?

I've never even heard of them doing a BBC show.
Cream have got some very good BBC sessions if you're into that band. The version of SWLABR is really great.
the cream sessions are ok not the best but are ok

EDIT- damm to slow there ok SWLABR is def a highlight
