Rock'n'Roll Marathon

One of the most fun, energetic marathons around, the Rock’n’Roll Marathon series visits more than 30 cities around the world, including Philadelphia in September. A series of stages line the course, and runners and spectators are treated to live music throughout. Clear Sound provides the audio equipment and mixing support for each of these stages, including Main Stage, where Big Head Todd and the Monsters performed . The Series began in San Diego in 1998, and now includes many stops in the U.S., as well as Madrid, Liverpool and Mexico City. Philadelphia has hosted the event for seven years, and Clear Sound has been there for each one. Currently, thousands of participants and spectators come out each year for this top-level international competition.

For the Philadelphia Marathon's entire 20 year history, Clear Sound has provided sound production at the start and finish lines along with more than a dozen stages throughout the race course. 

Intimate, natural-sounding dialogue in a sold-out theater. Crisp, intelligible announcements in a packed stadium. Exhilarating lights and music at an outdoor summer festival. A stirring sermon reaching every corner of a cavernous church.

Sounds like the work of Clear Sound - the Delaware Valley's best full-service audio, video and lighting company.
