Simultaneously with the Panart recordings from Havana, Tito Puente recorded a full descarga album in 1956, "Puente in Percussion". It is a percussion-heavy set of descargas featuring Mongo Santamaría, Willie Bobo and Carlos "Patato" Valdés. Like "Cuban Jam Session Vol I", the album features variations on mambo themes, although the focus of Tito's recordings is the percussion section, lacking a pianist to play the guajeos. The album featured guest bassist Bobby "Big Daddy" Rodríguez to play tumbaos on a couple of tracks. In 1957, Puente recorded his critically acclaimed "Top Percussion", the follow-up to "Puente in Percussion". It features Mongo Santamaría, Willie Bobo, Francisco Aguabella and Julito Collazo. The album closer is a 7-minute descarga-jazz with guest Doc Severinsen on lead trumpet.
