Last of the Bluesmen?

These gentlemen wailing at Farragut North well might be the last of the breed. Trios and larger groups like Spread Love are being driven away from the corner of Connecticut and K due to the loudspeakers that have been installed by the Gold Triangle B-I-D. The volume of this pre-recorded jazz and pop has been turned up, as if to dissuade the buskers from plying their trade, their art.
