Services Rolson Music & Sound is a family-run business providing sound system services, lighting, and now a mobile stage. Based in Los Osos, with 30yrs in the music business in our area prior to starting RMS in 2001, we have earned a reputation for dependable professional-level sound reinforcement for local concerts, car shows, graduations, conferences, weddings and receptions, banquets, auctions, political functions, law enforcement field days, Memorial and Veterans Day ceremonies, and many other events. Rolson Music & Sound is proud to announce an exciting new addition to our sound system business. We have just purchased a new StageMobile mobile stage! This is a beautifully constructed all-aluminum 16x20ft stage, available with a full set of guardrails, 2 sets of stairs, and skirting. It is, in fact, the same stage that has been used the past several years for the popular summer Concerts in the Plaza series in the San Luis Obispo Mission Plaza, and is perfect for a variety of functions.
