One: know of any good hypnotic drum music (with a variety of types of drums)

My only suggestion would be Robin "Adnan" Anders

Two: There's this one piece of music that beings with a kind of gentle whooshing, maybe
a little electronic in character, it builds in intensity, and then there are these sweeping
(words fail me) booms. I don't know if it's Vangelis or not but I do know that it was used
for the 3-2-1 contact segments when they were exploring Antarctica.

Not a clue. Loyal readers?

Three: do you know of a good catalogue of tribal patterns and their meanings?

Nope. Sorry.
