Yes yes I know there are MANY topics about blinking leds with music etc etc.
I'm going to buy these CCFLs http://www.ebay.com/itm/2x-BLUE-12-Car-CCFL-Cold-Cathode-Neon-Tube-Light-Lamp-/260821194735?pt=Motors_Car_Truck_Parts_Accessories&hash=item3cba2797ef&vxp=mtr#ht_5980wt_1274 and I want to be able to blink them with music since I can't fade them. I understand I'll need to use a solid state relay of some sort, but I can only find ones meant for AC voltage control. Can someone point me in the right direction on how to flash these?

The reason I'm not using leds is because I don't want the light to look like multiple points, but instead be solid. Unless there is some led kit available that diffuses the light...

Relay can operate with both , AC and DC. The same time, switching on/off  usually slow for regular relay. There are also solid state relay on a market, which is fast. Or you can build your own driver based on this drawings:

CCFL package includes rectifier (HV converter, probably, right name for it), so it's not clear how fast this devise on start-up. I mean, you could build a circuitry, but if there is a big delay in switching rectifier , than you'd also have to build another rectifier/converter...
