The 40^th Street Summer Series—co-produced by the University of Pennsylvania, The Rotunda, and University City District —usually takes place on the third Saturdays of May, June, July, August, and September at the green space behind the Walnut Street Library at 40th and Walnut. Activities, free giveaways, and performances begin at 6 pm. 

The Summer Series has grown into one of the most popular outdoor summer events in University City. This free outdoor series features internationally-recognized talent in one of “West Philly’s picturesque open green spaces” (Philadelphia Weekly). In the past, the Summer Series has featured internationally-acclaimed acts such as the Millennial Territory Orchestra, Man Man, and the Sun Ra Arkestra, playing free outdoor concerts that capture the soul of the neighborhood. 

2017 marked the 13th anniversary of the 40th Street Summer Series. Stop
