Formed when many of its members were music students at East Tennessee State University, Demon Waffle has been honing its ska sound. According to a press release the band “adds their own variations with old-school beats coated with down to earth lyrics that will entertain.” And Demon Waffle has a connection to Asheville, having recorded its debut, Eat Your Breakfast, at CollapseAble Studios. The band stops by Jack of the Wood on Monday, Jan. 7. 10 p.m., free show. http://www.jackofthewood.com.
