Here's some albums that may fit your bill. [b]Bushes and Marshmallows by C418[/b] Really odd sampling, ambience, and repetition strewn about. [b]Music Has the Right To Children by Boards of Canada[/b] IDM with droning beats and odd samples. [b]Selected Ambient Works by Aphex Twin[/b] Pretty ambient stuff [b]Endtroducing.... by DJ Shadow[/b] Fantastically beautiful trip hop with jittery vocal samples here and there [b]Lift Your Skinny Fists Like Antennas To Heaven by Godspeed You! Black Emperor[/b] It's technically Progressive Post-Rock but it has amazing ambient sections with emotive vocal samples that slowly turn into heavy instrumentation that's very energetic. This album is quite a commitment to listen to so be sure you're ready to bathe in audio limbo before you jump in. No links now but maybe later.
