Seattle-based indie studio Digital Eel have released a new soundtrack collection for Big Box of Blox, Dr. Blob's Organism, Weird Worlds: Return to Infinite Space, and Brainpipe: The Plunge to Unhumanity, the latter three having won the Independent Games Festival's "Excellence in Audio" awards in 2004, 2006, and 2009, respectively.

Titled VooDoo Interface: Sounds of the Purple Void, the album is available to stream or download at Bandcamp. You can grab each song for free as an MP3, AAC, or "just about any other format except DWR (digital wire recorder) and GPA (gas-powered audio)", but if you buy the release for $5, you'll also receive four bonus tracks, high resolution CD art, and more.

And if you haven't played any of the games yet, you can still download at least two of them for free: Big Box of Blox and Dr. Blob's Organism. The other two Windows/OS X games will set you back more, but they're both unique experiences worthy of your attention.
