Nice, but , i think after the voices at the debut there are not enough variations ( some effects on some precise points by ex ), and after +/- 1' 30 minute, sorry, but the melody is boring!, ouf!! after sometime the rythm turn more drill and it's better( but it's not enough!!), hum hum, it's just my opinion i m not a reference. otherwise i ve no words to say the rythmik is really really good and i like the voices, :) it's feel experience
