Ray Barretto (1929–2006), a.k.a. King of the Hard Hands, was a Puerto Rican jazz and salsa musician who was widely credited as the godfather of Latin jazz. He was also the first Latino to record a Latin song that became a hit on the American Billboard charts.

Barretto appeared on Sesame Street in Episode 0966 to explain Latin rhythm.
