AHH! After 3 weeks of sacrificing time and effort, I finally got my lights to be sound reactive. I'll put up a youtube video soon, but what I basically did is hook up a 110V/20V AC/DC converter and a small amplifier to an NPN transistor using some copper wire. Make sure the transistor can handle plenty of watts, current, and voltage. (Approx. >30V; >3A, >80W) Also make sure the converter can handle >80W, >3A.
Then just hook up two light bulbs that are 20V 40W and badaboom.
The louder the music, the brighter the lights. This means every time the bass drum plays, the lights get very bright. If you don't play electronica, just mic your drummer's bass drum through the amp that's hooked up to the NPN Transistor.
This whole project cost me around $15, $10 without Trial + error shizat. What you'll need: - 1 NPN Transistor (about $.79 ea.) - 2 light bulbs (about $3.50 ea.) - 1 Power Converter (about $10 ea.) - Copper Wire (free, you can use extra wiring from an old USB cord, ethernet cable, telephone cable, guitar cable, etc.) - Soldiering Iron or Alligator Clips (borrow from dad's toolbox) - a box/wiring plate (an old shoe box?) - small 10W-25W amp that WONT be needed when playing live shows ($30-100)
Without the amp I already had, it cost me $15 as priced. =]

Hardcore.
It'd be pretty sweet to get an IC (I don't know which one, my electronics skills aren't that good) that switches one light on and the other off when it gets current.
Then you'd have light A when you're quiet, and light B when you're loud.
