Home Puerto Rico Project BORICUA PIONEER: JOSEPH ESTEVEZ JR. a.k.a “JOE LOCO” (1921-1988)


How did the pianist JOE LOCO (Joe Crazy) acquire the nickname? Theories abound. According to Jose Mangual, Sr., “The ‘loco’ tag was hung on him around the mid-1940s after Verne Records recorded his tune, ‘Cada Loco Con Su Tema.'” Loco’s wife, Irma, begs to differ: “Joe suffered a head injury after being hit by a bus. Shortly after that, his friends began calling him ‘Loco.'” Another source suggests Tito Puente gave Loco the nickname. Perhaps we will never know the answer, but, without question, Joe Loco was talented and revered in Latin and Jazz circles.
He was born Joseph Estevez Jr. on March 26, 1921, to Puerto Rican parents Jose and Frances Estevez in Manhattan’s Hell’s Kitchen. At eight, he began violin and dance lessons and participated in the Stars of the Future project run by Spanish Harlem’s La Milagrosa Church. In 1934, he left school and went on the road. According to jazz historian John Storm Roberts, “Loco started as a dancer at the Apollo Theater and appeared with the Chick Webb Orchestra (featuring Ella Fitzgerald) in the 1930s.”
In 1937 a truant officer caught up with Loco and convinced him to attend Harren High School, where he befriended the music teacher, Charles Pickells, who taught him the rudiments of the piano and trombone (multiple sources indicate Loco started out as a trombonist). He studied music at New York University and specialized in the Schillinger System, named after Joseph Schillinger (1895–1943), which comprises theories of rhythm, harmony, melody, counterpoint, form, and semantics, purporting to offer a systematic and non-genre approach to music analysis and composition.
Loco began his career as a pianist with the Montecino Happy Boys (1938) when the band performed in Spanish Harlem. In 1943, at the height of World War II, Frank Machito Grillo’s pianist, Frank Gilberto Ayala, was drafted and replaced by Luis Varona. Shortly after that, Varona was drafted, and Loco replaced him. According to Jose Mangual, “Immediately after Loco joined Machito, the band sounded different because of his solo’s. They were hot! The dancers started calling us the Latin Count Basie Orchestra.”
In 1945 Loco was drafted into the U.S. Army Air Force. After discharge, he studied at Juilliard under the G. I. Bill. Also, he and Tito Puente worked as sidemen in Fernando Alvarez’s Copacabana Samba Band. Later, he joined Jack Lopez’s band.
According to Max Salazar, “One evening Loco substituted for (Pupi) Campo’s pianist Al Escobar and the event turned into a spur-of-the-moment event. Loco’s piano was searing hot, Tito Puente’s timbal and Johnny ‘La Vaca’ Rodriguez’s cascara made for an exciting, exotic sound that created delirium.” Fortunately, someone had the wherewithal to record the performance for posterity. The result is the album, Pupi Campo’s Latin Dance Party (Seeco, 1948).
Loco also took part in another historical event at the Park Palace on 110th Street and Fifth Avenue when he composed twenty original tunes, directed Julio Andino’s Orchestra, and challenged the Machito Orchestra to a duel. “It was a David and Goliath battle,” says Salazar, “except Machito was not slain.” In spite of the loss, Andino’s orchestra made a good showing.
In 1951, Loco’s trio made his first recordings for Tico Records. Shortly after that, George Goldner scheduled a recording session for Tito Rodriguez. When Rodriguez came down with laryngitis, he salvaged the session by recording Loco’s trio. The song Tenderly (1952) was a hit, and Goldner offered Loco a recording contract.
Loco also worked in jazz clubs such as the Blue Note, Denver’s Melody Lounge, The Apollo Theater, and Birdland, which transmitted Loco’s live performances via radio. Also, he participated in the Mambo USA Tour, which sold out Carnegie Hall and traveled to 56 cities.
At one point, unhappy with his royalties, Loco confronted Goldner, who wisely granted him permission to record for Columbia Records in exchange for a percentage of record sales.
In 1959, Loco and his family relocated to Los Angeles. The same year, The Pete Terrace Quintet released the album Going Loco. Also, to satisfy the Pachanga craze, Fantasy released Pachanga with Loco. Over the years Loco recorded for the labels GNP (Gene Norman Presents) and Orfeon.
According to Max Salazar, “By 1967, it was apparent Loco was losing his edge. “This was painfully evident on the album Puerto Rico 67, where it seemed that Loco’s fiery piano solos were a thing of the past.” Around the same time, Loco separated from his wife, partnered with Charlie Palmieri and Tito Puente, and formed the music-arranging company, “Bandaide.”
In 1968, Loco moved to Puerto Rico and took advantage of San Juan’s booming hotel scene. Also, he founded The Loco Recording and Publishing Companies and performed at a variety of popular nightspots in San Juan.
Joe Loco succumbed to diabetes on February 18, 1988. A veteran of World War II, Loco’s grave is located in Bayamon’s military cemetery, where his tombstone reads: “U.S. Army Corporal, Joseph Esteves Vargas.”
Boricua Jazz Pioneer Joe Loco was a consummate musician, showman, and a significant figure in the development of Latin music and Latin jazz. His impressive body of work is available on a broad variety of digital platforms and YouTube.
