Right now, I'd have to say Trinidadian artists. There are only a handful of Guyanese chutney artists today and most of them aren't that good. When you go to a party, you mostly hear chutney from Trinidadian artists.
There are some Guyanese chutney artists. Supertones Band, Mahendra Ramkellawan, Shatta Youth, Terry Gajraj, Kenrock.
this is just heat waiting to be started lol its pretty obvious that majority would agree to trini artists. There are more of them, and they are more well known.
