Episode 167: I met Casey Driessen almost 20 years ago when he was new to Nashville, fresh off a music degree from Berklee in Boston and full of new ideas about bluegrass and American fiddling. He became a key sideman for folks like Tim O'Brien and Darrell Scott. As a composer and arranger he made several solo albums and then refined a truly solo approach with looping pedals. He's become a cutting-edge authority on the innovative bow "chopping" technique that all up and coming fiddlers have to learn now. His latest record documents nearly a year of global travel with his family, meeting other musicians and cooking up tunes and sessions captured in the album and multi-media work "Otherlands."
