GSP In the Mix: Player One OURFest (Philadelphia)

At BOS Philly, we are proud to be a 501(c)(3) nonprofit organization honoring and reimagining the tradition of circuit parties in Philadelphia. Rooted in the original purpose of circuit parties—bringing people together to celebrate, connect, and support meaningful causes—we’ve evolved the concept to create events that are as inclusive and diverse as the community we serve.

Our events range from intimate gatherings to large-scale productions, all thoughtfully designed to provide a space where everyone feels welcome to express themselves, connect, and let go. Featuring top-tier production and DJs who bring a spectrum of sounds—we celebrate the joy and freedom that dance culture is all about while breaking boundaries often associated with traditional circuit parties.

At BOS Philly, every dollar raised is reinvested into elevating future events or donated directly to LGBTQ+ charities that make a difference year-round. By attending, you’re not only part of an unforgettable night—you’re helping to build a stronger, more vibrant community.

Whether you’re drawn by the music, the energy, or the opportunity to support a greater cause, BOS Philly offers an experience that honors the past while creating a brighter, more inclusive future. Together, we can reclaim and redefine what circuit parties mean for our community.
