Puget Sound Works 

A testimonial from the guitar player in Saruna. He also plays with Lee Oskar who helped write "Lowrider" and played harmonica on the track. "Mark Lacas is the fucking man, this thing has never ever sounded better, and whoever you’ve got in your Rolodex for fixing your devices, you gotta ditch that clown & connect with Mark. Satisfaction beyond all belief."
