Are you a diehard singing competition fan? Have you memorized every line to Pitch Perfect? Do you un-ironically call yourself a "gleek"? Do you prefer people imitating instruments versus actual instruments? Well, good news, NBC's The Sing-Off is coming tonight! Live at the State Theatre, recent Sing-Off champs Home Free, alongside season four finalists The Filharmonic & Voice Play and special guests Street Corner Symphony, will do their renditions of pop songs. Individual sets by each group, ultimate sing-offs and a couple other surprises, round out tonight's show. It starts at 8 p.m. and tickets are $10 to $39.50. (Stoops)
