When I was up at the local 5-Spot today for lunch, the proprietor told me of a band that recently played there whose bassist was plucking and bowing on a 7-string doublebass. He insisted that it was not an electric model, and that he wasn't confused. This fellow is pretty savy about instruments and jazz, and he was not pulling my leg either. I searched the web diligently looking for such a beast I would have surely thought to be extinct for more than 200 years and I have found that another band, the Paul Dunmall Quartet:http://www.shef.ac.uk/~ps/efi/labels/fmr/fmr155.html credits their bassist, Paul Rogers, as using a 7-string DB. Has anyone else heard of that recently?
