These and other performers can be seen at the Metropolitan Library System’s free Wizard Rock Show from 6 to 9 p.m. Sunday at the Midwest City Library, 8143 E. Reno in Midwest City, where fans can celebrate and mourn the end of “Harry Potter” series, whose final film opened last week.

The fifth-annual concert features five musical artists and groups, most named after various figures in the novels. Their tunes include various tributes to the franchise, from The Whomping Willows’ “Ode to Professor Sprout” and Lauren Fairweather’s “Howler.”

Kim Terry, MLS marketing director, said the popularity of the books and movies is due to their whimsical fantasy world that children and parents alike can enjoy.

The concert coincides with the last week of MLS’ teen summer reading program, “You Are Here,” which incentivizes children to read by offering prizes and gifts for goals met — something easily accomplished by reading the rather thick “Harry Potter” novels, Terry said.

“We want the library to be a place where people can come hang out, and have fun,” she said.
