Long before Los Angeles' dance music scene reached peak levels of cool, we had Doc Martin. Back in the '90s, the venerable house DJ held down a residency at Glam Slam as he built his reputation as a global house-music ambassador. Even when L.A. DJs weren't making a huge impact on the international circuit, Doc Martin was; in fact, he contributed a mix to the famed Fabric CD series in the early 2000s. Today, his résumé reads like a litany of the world's premier nightclubs. He's played the big spots from Berlin to Ibiza to New York, but the best thing about Doc Martin is that you can catch him here often. He's not just the cool DJ who happens to be based in L.A.; he helped build this city's house scene and remains a major nightlife presence. The local legend turns up seemingly everywhere, from big festivals to intimate rooftop parties, spinning sets that can be soulful, futuristic, deep, funky and surprising.
