Bispora's The Cycle is heavy progressive music with the perfect mix of ambience thrown in. Here are two mentions on 2001 year-end lists - this from Heavy Blog is Heavy and this from No Clean Singing that says
The Cycle is essentially one twenty-minute song that bounces between a couple of different genres as deftly as Between The Buried And Me do. The main motif of The Cycle is excellent. It is seriously one of the best melodies of the year.
