Wow, thank you, I'd never heard of him. "A bit of a proto-Little-Richard" seems a huge understatement. It seems Little Richard copied Esquerita's style. And Esquerita's look and sound on his youtube videos certainly supports that! e.g.
https://www.youtube.com/watch?v=ZUF81FcZHMA From that wikipedia page:
"Reeder has been cited as a key early influence on Little Richard ... his look and style were in a very similar vein, although Esquerita was much more flamboyant in the 1950s and his music played more wildly than the contemporary music of Little Richard. Reeder did not record until after Little Richard's initial early 1950s recordings for the RCA and Peacock labels and the later hits on Specialty. However, early Little Richard recordings made at WGST Radio Station in Atlanta do not show the style that was to make him famous. According to Richard, Esquerita did influence him and taught him to play the piano. In an interview...in 1988...Richard states that he saw Esquerita getting off a bus at the Macon, GA Greyhound bus station, but doesn't say which year, presumably in the early 1950s. There's a hint of a sexual connection between the two, but Richard also states that he was inspired by Reeder, and moreover, Reeder was inspired by Richard to go into show business.
Little Richard also had not intended to use what came to be his (and Esquerita's) characteristic style during his first New Orleans session for Specialty Records. The session producer, Robert "Bumps" Blackwell had been unhappy with Penniman's initial songs on the session, so, taking a break from recording, he went with Richard to a local cafe, where Richard jumped on a piano and began singing an X-rated version of "Tutti Frutti", in true Esquerita fashion. Blackwell felt that a cleaned-up version of the song with the same style of presentation would be just what his boss Art Rupe was looking for, and this song launched Little Richard's career in 1955.
