Thank you so much Jadizm!!! That one was driving me crazy. I used to own it a long time ago. Hey bud, the Roy the Boy is actually after the track I'm looking for. If you go to the time stamp on #21 it's right at that ambient acapella sounding track. Thanks for listening my friend.
That tune at 10:28 of the David Alvarado mix was bugging me; I found this tune which seems to contain the same piano riff but slightly slower. Not the track we're looking for but I couldn't find any other producers/releases that may have sampled or vice versa...https://www.discogs.com/release/191372-TNI-Grass-Chant
It's the AA1 'Primate Trance' track. Also missing the "Get on Up" vocals.
