Dunno about compilations but Stereo/Stereo Cool have a nice catalogue of tribal stuff ranging from darker sounds to melodic.
Pretty much one of the most definitive labels in the genre imo. I got like 20 releases on vinyl from 2005-2010.
Toolroom released some techier tribal stuff too but you should ask Coffey if he's still around, he seems to know his stuff (actually I lost a DJ mix battle against him in 2008 iirc
)
I also came across this guy Patrick Kroft who released a very groovy mixtape called "Tribal Trip"
