Local showman Colman Domingo revives his 2005 hit, A Boy and His Soul, for Thick House's 20th-anniversary season. Domingo's tour of his Philadelphia childhood offers a generous helping of the city's musical heritage: sweet-sounding soul by the likes of the Delfonics and the O'Jays. Many music critics have lionized Philadelphia soul, but Domingo's idiosyncratic take demonstrates the way a regional sound can shape memory and personality. Domingo is fresh off a Broadway run in the Tony Award-winning Passing Strange, but A Boy and His Soul still gives the fullest view of his dynamic talent.
