Tettix is going to have a hard time outranking the work he did on the Cool Pizza Soundtrack with any other endeavor (seriously, it's a silly name but it's a worthwhile download). However, his Solace soundtrack is worth taking note of - as it's for an imaginary game.

Solace is a game you will never get to play. A world built from the music up. Each song inspired a different piece of concept art/screenshot. I see the composition and concepts of the game with great clarity. But you can imagine whatever you like.

Every track has it's own associated "gameplay art" to go along with it. At first you with the game would exist but then you realize it would never match up to the experience you create in your mind - so just enjoy it for the proper soundtrack.
