Matt Mitchell (he plays guitar) and Marianne Dissard (she doesn't, she sings) form a duo. But they're also solo-artists. And part of bands. And they join each other for special projects. Like the album Christmas in Tuscon, featuring band from the Tucson area playing x-mas songs: Al Perry, Naim Amor, Bob Spasm, Solace Bros., etc. On this album, Matt does a great instrumental rendition of Sleigh Ride, while Marianne (with Matt on guitar) covers Jona Lewie's Stop The Cavalry, with slightly changed lyrics.
