As temperatures soar outside, residents of West Chester can enjoy free jazz inside. Every summer for the past 34 years, alumni from West Chester University’s premiere jazz ensemble, The Criterions, reunite to perform jazz, big band, and swing music in a free, public concert. The concert takes place Thursday, July 18, at 7:30 p.m. in the Emilie K. Asplundh Concert Hall, Philips Memorial Building, 700 S. High Street, West Chester.
