The title track of Stephen Riley's 2018 album, "Oleo" is Sonny Rollins's iconic rhythm changes contrafact that has been a cornerstone of the jazz repertoire since its debut on the 1954 Miles Davis Prestige album Bags' Groove. Built on the chord progression of Gershwin's "I Got Rhythm," the 32-bar AABA form in B-flat at approximately 252 BPM provides the quintessential bebop blowing vehicle. Riley takes two focused choruses of tenor saxophone, bringing his characteristic lightness and behind-the-beat phrasing to rhythm changes, arguably the most fundamental improvising framework in jazz after the blues. Trumpeter Joe Magnarelli follows with three energetic choruses that drive the tempo with bebop authority. As the album's namesake, this performance makes a clear statement about Riley's musical allegiances, situating his art firmly within the tradition of Sonny Rollins and the broader tenor saxophone lineage. Rollins's influence on Riley extends beyond repertoire to encompass an entire approach to improvisation: thematic development, rhythmic freedom, and the ability to tell a story within the changes. The recording captures the essence of what makes rhythm changes such an enduring vehicle for jazz improvisation, and Riley's interpretation connects his Lester Young-influenced aesthetic to the Rollins tradition in a way that feels both natural and revelatory.
