Pastorius Park Summer Concerts take place for seven weeks, mid-June into the end of July, every Wednesday at 7:30 p.m*. Enjoy a lineup of bands drawn from many musical genres performing against the backdrop of one of Chestnut Hill’s most majestic areas. This event brings together neighbors and families from Chestnut Hill and surrounding communities. Swing That Cat is a Sonic Cocktail of Jump Jive and Wail ~ â¯Jump Blues, swizzled with Swing, a dash of Cabaret and a splash of Bourbon Street. This female-led band backed by crazy cats that all howl, “Yo Philly” with horns, guitar, bass and drums, has earned their stripes at over 400 shows from NYC to DC and streams around the world. Blending a revival of styles, rhythm and rumble, this band guarantees to make you shimmy, shake, and leap off your seat to dance your tail off!
