Last year, in the attempt to emulate the WMMS Coffee Break Concerts that were so popular here in the 1970s and 1980s, the Music Box Supper Club teamed up with locally based oWOW Radio for a new, summer-long Happy Hour Concert series. The program has returned to the Music Box this summer and features both national and local acts. The radio station will broadcast the hour-long concerts live. Tonight, blues singer-guitarist Kristine Jackson takes the stage. (Jeff Niesel)
