This just popped up over at solesides.com: the vocals-included version of an instrumental track that appeared on Shadow's 2006 album The Outsider.

Zach screams over the rampaging drums, bass, and scratchy guitar, making it similar to what Zach is doing now with Jon Theodore as One Day As A Lion. There are some keyboards and added noises, but this is a high powered frenzy of a song and unless you're a headbanger you might want to be a little angry when you take a listen.

One of the other two songs they did together, "March Of Death", was available for free a while ago and can also be heard at YouTube. The vocal version to the other song "Instrumental 3" is nowhere to be heard though... yet.
