Dave hasn't just written the definitive book on street musicians, but he is a goddamn great rack harp player. Listen to the first position stuff he throws down here.
I love playing on the street and do so in two different styles. Here is our roots/ blues type and we also do a rockabilly thing. No harp on this one but its a fun tune
Dave is highly regarded here in Victoria, not only as a OMB busker but also a great musician and blues historian. Plays a great variety of blues, everything from traditional to 'bar blues' (what I call it as it gets closer to rock). AND he is a super nice guy to boot!!
