Wonderful idea Luke! Some of the KISS fans did something of the same sort (KAOL-KISS Army On Line) a few times to raise money for Alzheimer's research! Pretty neat project really -people from all over the world sent in tracks for the cds.

Although I really don't think anyone on here would honestly like to hear me sing....and I'm not quite good enough on drums to warrant a drum instrumental...I would gladly help with any cover art/graphics you might want though...
Cheers!
