Where in Prague does one go to see/hear bluegrass music? We're going to be there this weekend actually.
I have only ever come a cross a bit of Blue grass in Prague was in a pub called Na Vandru on Cimburkova in the Zizkov area of the city.It was really a jam session of several musicians and they did a variety of stuff with a bit of Bluegrass thrown in.This was a few years ago so I know it not much help, might be worth checking the ex-pats website and asking there.
