Great posts! Real bluegrassers won't be loud, obnoxious and crass in a jam circle-nor will they take over workshops. However, playing other genres in bluegrass jam circles at bluegrass festivals especially on non-conventional instruments in non-conventional keys does open oneself up to extensive criticism, many times rightfully so in my opinion (people go to bluegrass festivals to play with bluegrassers in bluegrass jam circles)......just a couple of thoughts....
