It's a mixed-up, muddled-up, shook-up world: Dance-music artist runs his life like a business, rigorously following a marketing strategy and booking venues based on potential profit margins. He's world's richest DJ for third straight year. Dance-music corporate executive views his business as "an art not as a science," despite admitting he doesn't know much about the particular art in which he is engaged. He appears on the verge of running that business into the ground. Maybe CALVIN HARRIS, not ROBERT F.X. SILLERMAN, is the dude who should run SFX ENTERTAINMENT... PITCHFORK's 200 BEST SONGS OF THE '80s, topped by the wrong PRINCE song and the right MJ song... DEE BARNES accepts DR. DRE's apology; MICHEL'LE does not. Which is not even remotely a contradiction. They are victims, and their responses are personal and equally valid. But because, as BARNES puts it, "This is bigger than me, and bigger than hip-hop," I wish DRE would open up and say more. His two acknowledgments of his abusive past, in ROLLING STONE and the NEW YORK TIMES, have both been vague... YO LA TENGO will be the house band on NPR's "MORNING EDITION" today, meaning they'll be live in the studio playing the "button" music between segments.
