Seem like someone was upsetting before the Upsetter... using the name *"The Upsetters"* before Lee Perry...
1965 (at Studio One) and what Ive heard doesnt sound like Lee Perry... Im quite used to his ska vocals.
*look it here* www.geocities.com/litelet/upsetters.jpg
So if its not Perry, who's the first original UPSETTER....??
You can have a listen here...
