Groups
The A Cappella Project - Philadelphia runs multiple groups every year in the Philadelphia area.
Summer Groups
Project-Philly sponsors two full-size co-ed a cappella groups every summer. These groups rehearse during June and July and present the Annual Benefit Concert in early August. They are made up of collegiate singers (home for the summer) and young adults who have graduated from college. Each group is named after a color to distinguish it from other groups (i.e. Project Blue, Project Orange).
Reverb
When Project-Philly's collegiate singers return to school and their school a cappella groups each fall, the adults come together to form a single co-ed group called Reverb. It gives them an opportunity to sing throughout the academic year, just like their collegiate counterparts. Reverb runs from October to April, with a break in December-January. Instead of live performances, Reverb focuses on recording their repertoire.
