ghost, I agree 100% with you on jazz in the 1980s. There's tons of interesting stuff there. TONS. You've just got to dig a little -- just like in the 1970s.
felser,
I don't have that set -- but I do have Carnival and Zeitgeist on LP. Figured that was enough. But perhaps I'll plop for the set some day.
Shrdlu's recommendation of Expansion (Double Helix, 1973) really catches my eye because it was made during the 1970s -- unlike the stuff in the Mosaic set. I figured Expansion might be something worth including in my 70s survey. For the same reason, I've also wondered about Zeitlin's Soundings (1750 Arch, 1978).
Both look interesting. Unfortunately, I haven't heard either of them. There's only so much time and $$$ to go 'round.
