I haven't been able to work out from info given on the torrent site what the overlap of players between bands was. I know that News From Babel was a side project from Henry Cow when it first apeared or certainly had a lot of overlapping members. I don't know the other 2 bands Music For Films and Oh Moscow (not sure if the first of those is actually a bandname or a description). So have wondered if there were a few musicians who were onstage throughout the whole performance. Which would be good going for septuagenarians.
Anyway the Barbican show is great and I haven't listened to the Huddersfield show which just appeared on Dime a few minutes ago.
