DEF CON 21 - The Official Soundtrack!

Thanks to the huge success of DEF CON's 20th anniversary compilation, we've brought it back again and stepped up our game. This year, we present you with "DEF CON 21: The Official Soundtrack:" 20 tracks of pure nerd fuel for hacking. The compilation features many of the talented acts in attendance at the conference, like BT (seriously!), Faderhead (for real!), and far beyond that with generous submissions from the likes of PANTyRAiD and Gramatik.

As if that wasn't enough, this release is completely free/donation-based, with 100% of the generated revenue going straight to the Electronic Frontier Foundation (EFF /, a 501(c)3 not-for-profit dedicated to protecting our Internet freedoms and privacy.

Get on over to the Gravitas Recordings (the awesome label donating their time, energy, PR skills, and distribution networks to the cause) Bandcamp release page to grab this sonic goodness, check the full track-list, and ***DONATE***!
