I have another song in the tank, I'll officially post it up on NewGrounds the 19th. Hopefully by then I'll have another one ready.

In any event, I post mini updates on Twitter:

Mostly I post up stuff on my progress on authoring for the Rock Band Network. If you're a band and you'd like to get your music in Rock Band, drop me a line :)
