Hmmm... Thanks for all the suggestions guys. Much appreciated. I have looked on the Roger Sanchez 2003 disk and found the tracklisting but no mention of it:
Soul rebels - the revolution will not be televised (plastic music remix)
Boca grande - push
Gattaca - supasax
Emmanuel - guajira
Rise ashen - second wind
Vibe residents feat dragonfly - the dj's calling
Dj oliver presents noche en granada - free my soul
Jason jinx feat paul alexander - your first time (jinx pull remix)
Sandy rivera feat haze - changes 9ben watt remix)
Jay-j & chris lum - freaks like us.
It IS a male vocal but not noticeably black. fairly mid tone to be honest.
I haven't been able to find a sample or in fact any more iinfo on the other suggestions....
