Just when you thought that turntablists in the vein of Philip Jeck or Martin Tetrault couldn’t take the experimental form any further, Toronto’s Mike Hansen steps in with At Every Point, a five-part suite of rhythmic panning, jagged aural assaults, and deconstructionist musique concrte. Abstract turntablism has a nasty habit of taking itself too seriously, but that’s not necessarily the case with Hansen; try on the rock-show tribute “Once Held A Lighter High in the Sky,” that mimics crowd cheers while scribbling noisy guitar remnants all about the stratosphere-heady stuff.
