The Brothers Comatose are a lively string band whose repertoire spans the roots range of Americana, from bluegrass to country and beyond. This quintet has a fairly large following, no doubt due in large part to its exciting stage presence and high degree of musicianship. You can find out for yourself at Humbrews at 9 p.m., where local pickers Fickle Hill will provide the opening salvo ($25, $20 advance).
