Folk-music has found a renaissaince is the most nano of micro-venues: people's living rooms, promoted by listservs.
Concert-goers bring the chips, dip and beer. A basket is set out for the suggested $10 to $12 donation for the musicians, and the living room, dining room and family room are filled with people wanting to hear folk music.
With few venues willing to hire folk acts and few middle-class suburbanites willing to make the schlep downtown, search out parking and elbow other patrons to get the bartender's attention, folk house concerts are quietly spreading like wildfire with the help of e-mail and Internet advertising.
