Pittsburgh Track Authority is back. After a five year hiatus from releasing music--during which time PTA maintained focus on expanding the catalog of their labels Pittsburgh Tracks, Love What You Feel, Machine Age Records, and Sleeve -- Preslav and Adam are back with a rejuvenated outlook on music and a renewed sense of purpose. The new album titled PA System is a collection of house and techno written to serve as a document of the past 18 months. As always with PTA, friends near and far, old and new, were a part of the writing process and the album includes collaborations with C. Scott, Santiago Salazar, Stuart Bogie, Nic Offer, Samurai Velvet, John Hall, and Kenny Peagler.
