Tettix - free album downloads and fun game
There is this excellent free flash game called My First Quantum Translocator by Cellar Door Games which has a few similarities to Portal. You can play it here. I looked into who composed the music, and Tettix came to the front. Formerly "Cicada" Tettix is Judson Cowan and currently has 17 free albums up for download on his website -- donation highly suggested! He has composed music for The Cartoon Network, Nike, Relevant Films, Budweiser, Diesel, and many others. I'm sure there is a song or two on his website that you will enjoy.
