Pop a Dramamine, slap a patch behind your ear, and grab ahold of the railing, because Tolga Fidan’s debut EP “Now I´m Weak” lurches like a dinghy on the high seas. (Might as well throw on a slicker, too, because you’re gonna get wet.) You haven’t heard a synth swell as seasick as the one on “Abstract Prologues” since Motiivi:Tuntematon’s sinking tanker of a track, “1939.” But as woozily as this 12″ rolls, it never loses its grip on the floor: all three tracks are solidly grounded in the blunt, toe-stubbing funk that’s become a trademark of Berlin’s Vakant label, home to mega-talents of minimal like Alex Smoke, Mathias Kaden, Onur Özer, and Robag Wruhme.
