From what I know, I think they're regarded a bit like Peel Sessions were over here (except in an hour long studio concert type format and, usually, by more established artists)
I've got performances by a number of bands on my pc at home - but the recording I've got of the set Gemma did is probably my favourite as the sound quality is superb!
Bonsoir...

There are also White Sessions which I think are recordings of proper concerts...
