With the Def Kith EP, the usually mononymous Martin Dosh and Jon "Ghostband" Davis debut their techno-addled, IDM-damaged brand of bass-blessed dance music. Across these three or four generous cuts ("Twin Speak" is digital only) we hear two "one-man-band" types becoming a single machine. It’s the rhythm section’s revenge as the respective drums and bass of countless jazz and odd-rock ensembles put their improvisatory chops to work, funneling a lifetime of wild musical obsessions (Sun Ra, Squarepusher, the RZA, Caribou) into their live electronica.
