I. Um, try a lot of the spacier side of Tarentel. You can check out such tracks from the library as:
Fear of Bridges 1-6
Welcome
Tarentel 1
The Waltz
Adonai
Popol Vuh
II. There's a band called "Stars of the Lid" that'd be good. go to
http://epitonic.com and search them out (free mp3s). At that same site check out "A Small Good Thing" and "Labradford."
III. Definitley not Blink 182.
IV. A lot of Mike Oldfield's output could fit this genre. I'm specifically thinking of "The Songs of Distant Earth" and "Tres Lunas."
That's off the top of my head... I'll drop more if I think of it.
