Not sure if anyone else in here is a wicker man nut like me, and have sadly let it shape your life a little too much (lol), but I recently sampled the soundtrack song 'lullaby' into a dreamy sort of ambient house track called 'Midsummer', and because of the original samples beautiful descending Dorian melody, it became a study in modes, and I tried to write as many interlocking polyphonic melodies to get a real dreamy feel. Let me know what you think!
Also run through my friend's Reel to Reel tape machine for fun
