Pucho began recording in 1963, and really hit his stride between 1966 and 1970, when he cut over half a dozen albums for Prestige. On these he helped pioneer a style termed Latin boogaloo, which mixed jazz, New York-style Latin music, R&B/soul, and the sort of funk that was just emerging from James Brown and other performers. Pucho wasn't afraid to mix up his material on his LPs, which placed originals by Brown and the Latin Soul Brothers next to covers of tunes by Herbie Hancock, the Temptations, the Beatles, Duke Ellington, and John Barry.

When his brand of Latin-soul-jazz fusion started to fall from commercial grace in the early '70s, Pucho disbanded the Latin Soul Brothers. For the next 20 years, he made his livelihood by performing conventional Latin music in the Catskill Mountain resorts of New York State. In the early '90s, however, Pucho's back catalog began to generate interest in Britain, where he was a hit with the acid jazz crowd, and where several albums were reissued by the Ace label. Happily, he made a return to Latin-soul-jazz-funk with his 1995 comeback effort, Rip a Dip, which found his skills intact. How'm I Doing followed in mid-2000.
