Stratus was SoCal's preeminent alcohol-free, under-21 dance club. Located in Casa de Oro, a San Diego suburb at the foot of Mt. Helix, the venue attracted young adults from as far north as Los Angeles. The club had its grand opening in May 1978, when disco reigned supreme. A "Saturday Night Fever" illuminated dance floor was recreated in the center of the club. Throughout the years the music format evolved to accommodate changing musical tastes of the club's patrons, which included soul, new wave, Gothic, hip-hop, rap and live music. Some of the artists who performed at Stratus were Big Audio Dynamite, The Chameleons UK, The Mighty Lemon Drops, L.A. Guns, Faster Pussycat, Nocera and the Fat Boys. Weekly promotions were hosted by San Diego's top radio stations and on-air personalities: 92.5 FM (soul) and 91X Rock of the '80s. After nearly 10 years of being the epicenter of entertainment for young adults in San Diego County, Stratus closed its doors for the last time on June 3, 1987.
