"One for Daddy-O" is a soulful minor blues composed by Nat Adderley for his brother Cannonball's 1958 Blue Note album Somethin' Else. Set as a 12-bar blues in B-flat minor at approximately 108 bpm, the tune features one of the album's most expansive solo sequences. Cannonball Adderley opens with four choruses of alto saxophone, his big, warm tone and gospel-inflected phrasing perfectly suited to the minor blues setting. Miles Davis follows with five choruses of muted trumpet, building a solo of remarkable patience and architectural beauty. Pianist Hank Jones contributes two refined choruses, after which Adderley returns for two more alto choruses that bring fresh energy to the proceedings. Davis then takes two additional trumpet choruses, and Jones closes with a final chorus. This extended, multi-round solo structure gives the performance an almost jam-session-like quality, with the soloists circling back to find new ideas in the same harmonic material. The relaxed medium tempo and minor-key tonality create a late-night atmosphere that brings out the most expressive qualities in each musician. The track demonstrates the depth of invention possible within the simplest of jazz forms when played by masters.
