Undoubtedly one of the non-Gotye, non-”Call Me Maybe” songs of the summer has to be Usher’s Diplo-produced “Climax,” an understated, dub-indebted track that provides a really jarring counterpoint to the club-ready sounds that presently dominate the radio waves (and the subsequent singles from Usher’s new album, sadly). TV on the Radio’s Dave Sitek took his turn reworking the track, and opted for a version that’s even more dub-centric than the original. Usher’s falsetto hovers above skittering electronics in a less-bassy, less-percussive cut of “Climax” that feels so claustrophobic it pushes the track underwater. You’re probably thinking what I’m thinking, aren’t you; when is Sitek going to do the same for “Call Me Maybe”? What the world needs now more than anything is a feel-bad version of the feel-good song of the summer, and enclosing 27-year-old Carly Rae Jepsen’s pubescent enthusiasm in a dark and watery sonic cage is probably just the thing to do it.
