Black swans and wormhole wizards
I always preferred instrumental work or soundtracks. The albums that work best for me are: Elecrtic Tears by Buckethead. Great atmospheric guitar work. the Machinarium soundtrack. Great game and interesting music. Ghosts I-IV by Nine Inch Nails. It's a recent album with no vocals. Colma by Buckethead again. A very peaceful album to work to. the World of Goo soundtrack. A lot more variations than Machinarium, but still enjoyable. Black Swans and Wormhole Wizards by Joe Satriani.
