You might check out Amos Hoffman, Evolution, featuring oud. Also, Eric Freidlander's Broken Arm Trio featuring cello, bass and drums. Lastly, two dates by bassist Buell Neidlinger featuring his Buellgrass band, Big Day at Ojai and Swing Grass. As far as I can tell, Neidlinger has reissued some of Big Day at Ojai as a cd called Across the Tracks.
