The six hundred and fifty-third album: #653 Coldcut - What's That Noise?
The word noise applies to a lot of this album, though not in the derogatory way that's normally used. The tracks mix a lot of sounds together, combining hip hop with a heavy dose of electronic music in various places. It's listenable, but pushes the boundaries of what I can really enjoy, but the experimentation involved in that is really nice.
