The late Nujabes is easily one of the masters of creating sounds and moods in the spirit of rap beats. He was able to create soundtrack aesthetics with boom-bap beat production that was unmatched. The Japanese great passed in 2010 due to a car accident. I saw this clip today and man was moved! A group of 2nd graders from Namsong Elementary School out of South Korea recreated the track Aruarian Dance Dance. If you get a chance search for his music via youtube. There are physical copies of his music floating around and digitally all you find are a bunch of tribute tracks and covers.
