The band Mardo is running a contest to give away a theremin. The entrance requirement has been changed - not you just have to send them an e-mail to be entered into the contest! To sweeten the deal, they'll throw in an autographed photo of the band to the winner.
Details can be found here.
Folks, I've listened to the Mardo album about 20 times through now, and it just keeps getting better! This is a completely unsoliticed plug for a great band! If you like rock music, you should definitely check them out. Listen for theremin on the song "Son".
Good luck!
