for the answer to the Zappa.

Finch's two best are "Glory of the Inner Force" and "Galleons of Passion" - both are mid-70's and have very long all-instrumental tracks. I believe they are Swedish or Norwegian. World-class guitar.

Another interesting band of that era was "Birth Control". They have a song about lying in a hammock (I am not making this up).
