White-beat pirates can come home from Jamaica with riddim realness, or sand in their shorts. Producers Diplo and Switch, a.k.a. Major Lazer, definitely do JA right. Recorded at Kingston's legendary Tuff Gong studios, this EP twists dancehall and dubstep into kinky new directions. M.I.A. gets militant on "Sound of Siren," and a Thom Yorke remix of "Jump Up" (from Major Lazer's 2009 debut) spikes a naughty party jam with futurist spookiness. The best moment, though, might be "Good Enuff" — a roots-reggae tune with sweet vocals from Canadian Lindi Ortega that provides a little soul amid the gangsta beach bingo.
