I believe it is Tito Puente.
Tito Puente has recorded at least 2 versions of Fiesta A La King. One version in the 70s and one in the 80s.
This one sounds like the 70s version with Tico Records.
You can find it in the big Tito Puente compilation 50 Years of Swing. The 80s version is even more jazzier - recorded with Concord Picante Records.
