IT’S HARD TO BELIEVE, but the incomparable Marcus Miller just turned 50. I was lucky enough to score an invite to his big LA bash, and it was an experience I’ll never forget. Hosted at Hollywood’s intimate Catalina Jazz Club, us lucky attendees we’re treated to a loose evening of fun and music, all delivered with a healthy dose of Miller’s inimitably cool vibe. After thoroughly indulging in the killer buffet and open bar, everyone sat when Marcus and his crack band took the stage with Stevie Wonder’s “Higher Ground.” As the night rolled on, illustrious audience members made their way to the stage for a host of world-class jams. My highlights: George Duke bringing the funk to Beethoven’s “Moonlight Sonata,” and, in what was one of the coolest musical events of my life, seeing Herbie Hancock play the hippest “Happy Birthday” the world has ever seen.
