Stephen Riley's performance of Bronislaw Kaper's "On Green Dolphin Street" on the 2018 album Oleo features some of the most extended blowing on the record. The 32-bar ABAB-prime form in E-flat, played with a Latin feel at approximately 191 BPM, provides a rich harmonic canvas for two lengthy solos. Riley opens with four choruses of tenor saxophone, bringing his floating, Lester Young-influenced approach to a tune that has been a jazz standard since Miles Davis's celebrated 1958 recording. Trumpeter Joe Magnarelli follows with four equally expansive choruses of his own, and bassist Jay Anderson closes with two choruses of acoustic bass improvisation. The tune's distinctive structure, alternating between a Latin A section and a swinging B section, creates built-in contrast that keeps the extended improvisations dynamic and varied. Riley's four-chorus solo demonstrates his ability to sustain creative invention over an extended form, building gradually in intensity while maintaining the relaxed, unforced quality that defines his playing. The recording captures the working relationship between Riley and Magnarelli, whose contrasting approaches to the same harmonic material create a compelling dialogue across their back-to-back solos. The performance clocks in as one of the longer tracks on Oleo, reflecting the musicians' deep engagement with the material.
