The last.fm support team relates there is no way to differentiate bands with the same name, so here is a breakdown.

The earliest well known ensemble to use this name was:
The HUB - interactive computer music

Since 1985, The Hub has been one of the first "computer network music" ensemble consisting of John Bischoff, Tim Perkis, Chris Brown, Scot Gresham-Lancaster, Mark Trayle and Phil Stone. The Hub grew from the League of Automatic Music Composers: John Bischoff, Tim Perkis, Jim Horton, and Rich Gold. Perkis and Bischoff modified their equipment to allow more musicians and founded The Hub.

They have collaborated with Rova Saxophone Quartet and Alvin Curran. They currently perform around the world after a hiatus. Their latest release on John Zorn's label Tzadik label is called Boundary Layer and is a 3 CD, 23 year retrospective of the groups work.
