I'm somewhat amused, happily, that there is excitement about this set, and that Mosaic considers this music worthy of reissue. At the time these records came out, nobody bought them, and they were considered stiffs (from a sales standpoint) at the time. I know, I'm a dealer, and they did not sell!
I saw the group live around 1992, and they burned! The "Live in Tokyo" (which apparently is not included) is probably the best thing this group released.
Anyway, I'm glad that a new generation of listeners is getting achance to hear this music which was largely ignored at the time.
I don't recall any electronic drums - I guess I'll have to go back and listen again.
