At the Studio at the Sunset Marquis Hotel & Villas, in West Hollywood, catering to an artist's needs is easy: You just order room service. The recording studio, run by Jed Lieber, is housed in an isolated corner of the lavish hotel's parking garage. With a smoking lounge–meets-bordello interior, the fully-equipped, intimate space offers an alternative to traditional recording studios. Back in the day, the Sunset Marquis was home to a Rolling Stone or two, but today musical megastars (or mega corporations) like U2, Jeff Beck and Aerosmith use the studio as a refuge from the rigors of touring. In fact, the hotel is creating a new parking garage big enough to accommodate their tour buses. It's a home away from home, and a secret studio for high-profile rockers. 1200 Alta Loma Road, W.
