"Pent-Up House" from the 1956 album Sonny Rollins Plus 4 is one of Rollins's most enduring original compositions, a catchy 16-bar theme in G major that has become a jam session staple. This definitive recording features extended solos from all four principal musicians at a medium swing tempo around 190 BPM. Clifford Brown opens with six searing trumpet choruses, his fleet lines and brilliant tone establishing a high standard for the soloists who follow. Rollins matches Brown's energy with six tenor saxophone choruses of his own, employing his signature thematic development approach. Richie Powell contributes six piano choruses, and Max Roach closes the solo section with two explosive drum choruses. The competitive interplay between Brown and Rollins on this track is legendary among jazz fans, representing two of the greatest improvisers of the 1950s at the height of their powers. The tune's simple, memorable melody and straightforward harmonic structure make it an ideal vehicle for extended improvisation, and the musicians take full advantage. This session, produced for Prestige Records, captured a once-in-a-lifetime meeting between Rollins and the Brown-Roach Quintet. "Pent-Up House" has since been recorded by countless jazz musicians and remains one of the most recognizable hard bop compositions ever written.
