1) The acoustic singer songwriting team of Emily Saliers and Amy Ray, better known as the Indigo Girls, is in concert tonight as part of the Allegheny County Summer Concert Series at Hartwood Acres.

Together they’ve combined for a nice musical synergy extending over several decades. Their latest album is Look Long. 7:30 p.m. 200 Hartwood acres, Hampton and Indiana Townships.
