Anyone knows where are the vocal samples from? Thanks.

it's mainly maxing shouting 'let it move you' and other mc'ing

no idea for the samples tho ie 'let it rock you' and that "waahh! waahh!" voice.

most likly from a late 80s us hiphop accapella (which one is anyones guess) not always acapellas though,alot of hiphop of that time had bits at the end of each bar where the beat would drop out completly in the mix and people would sample any voice in that time.
