This is not a mistake, this track is recorded by Nicolas Jaar himself assisted by a live band! Rework of South African jazz pianist and composer 
Abdullah Ibrahim's best pieces (you can listen to the original 
here). It's a style typical for Nico's work - very deep and groovy bassline, solid claps and all this followed by a live band instruments taking care of this being faithful to the original and simultaneously creating a perfect bridge between jazz roots and modern electronic. Recorded live in one take which also shows real talent and class behind this track.
