Favourite Van Der Graaf Generator Album?

I guess if you include prog bands that improvised from scratch onstage you'd have large pieces of Henry Cow's Concerts, some stuff from the Crimson live albums, and so on.
Tangerine Dream's Ricochet and Encore are almost entirely new/improvised music, but also questionably "live".

i highly rec the Maida Vale sessions too!!

even the recent Merlin Atmos live album is good

(plus it has VDGG handling some typically Hammill solo songs like Flight and Gog)

I do love them live around 75-78 cos they get really intense and have guitar and stuff.
Vital in the remastered form for the 2005 reissues is pretty good and I think has more David Jackson in as part of the remaster process I think. But there are a load of live sets around too. By the end they could rate as a pretty great dark post-punk band so hope there were a stack of people discovering them at the time. Like if John Lydon cited them do hope it lead to some people finding out how good they were and seeing them at this peak, one of several but others were years earlier too. Like not that they don't stand on their own feet since they did seem to be pretty marvelously maverick.

the maida vale sessions are fabulous, the version of "darkness" on there is wonderful. i don't think it's on the maida vale sessions proper, but the expanded version called "after the flood" has some wonderful material too - great version of "killer" and as i've already said, i'm really fond of "necromancer" - really fun '68 version here.

yeah think I mentioned turning up my copy of After The Flood a few days ago.
