Cain Park kicks off its theater season with the five-time Tony Award-winning musical Rock of Ages. Set in Los Angeles, the musical tells the story of Drew and Sherrie, two kids who chase their dreams in the big city and fall in love. You won’t want to miss the big hair and stellar score that features songs by ’80s rockers such as Journey, Styx, REO Speedwagon, Foreigner, Pat Benatar and Whitesnake. Tonight’s show begins at 7 in the Alma Theater, where performances continue through June 25. Tickets are $25. (Niesel)
