Well I went to check Preston Reed's website to see if his Scotland-based booking manager had booked him anywhere in the WashDC area this summer and saw his tour dates are all over the British Isles & Scotkand for the next 3 months.
So if anyone on the other side of the pond wishes to see a "true"
12 string virtuoso then Preston Reed's tour dates should bring him near enough to some venue within reach.
Definitely worth an evening.
