Red Fang have just released a FREE acoustic EP! The EP was recorded this past March in London as an Absolute Music Bunker session for TeamRock.com. Download/stream your copy here:
Bandcamp - http://redfang.bandcamp.com/
Need to give them an "email address", and they say "We won't share, sell, or be jerks with your email address".
I have signed up with my real email and have had no issues.
Music is similar to QOTSA, Mettalica, Soundgarden.
Other free music to found on their site http://www.redfang.net/
