This thread inspired med to dig out World Machine, pull out the Luxman 2 channel pre connected to the Carver TFM 45 and let the SDAs rip. No need for a sub. Wow, these guys are good. This particular album was a fusion of pop, prog and jazz, wonderful lyrics and harmony and a band that cooks on many levels (at least 42). I don't know why they faded. Every bit as good as some of the prog giants of the 70s...maybe just too late.
