Spotted in the Staples Center at Sunday night’s 54th Annual Grammy Awards: Thomas Wesley Pentz, a.k.a. Diplo, Mad Decent kingpin and nascent hobnobber, waiting in an outrageously long line for some much-needed pre-televised ceremony grub from California Pizza Kitchen. No idea if he ever got that pizza. But tomorrow, Diplo (via Mad Decent imprint Jefrees) will drop “Express Yourself,” an implacable, Howitzer-like monster that features New Orleans bounce-r Nicky Da B. Check it out below and get excited for the former’s forthcoming (and first) book 128 Beats Per Minutes. It’s due in April.
