Here's a video of Marty performing one of his solo tracks at a fundraiser for PDX Pop Now festival in Portland. The track is called "NCh'i-wana's Revenge". Marty's got a whole album of solo tunes, which hopefully will see the light of day soon.
Speaking of PDX Pop, those of you in Portland should totally go to the festival weekend! Info here: http://www.pdxpopnow.com. Fun fact: I helped start this festival when I lived in Portland!
