I know a couple of VERY good musicians who have 'Been There and Done It' so much , that when they are on their own they tend to improvise round the tunes , which CAN sound 'flash' to the basic Folkie . As a guy who started in Jazz , I can see what they are doing , but friends of mine just think 'Flash', NOT Damn Fine Musician ! A Classic example is Tom McConville - On his own he gets VERY esoteric , but catch him duetting with Pauline Cato and Oh What Beautiful fiddle !
