"The Collector" from Wayne Shorter's 1966 album Adam's Apple is an extended, free-flowing performance that features four soloists exploring Herbie Hancock's composition at a brisk 267 BPM in E minor. The absence of a defined form structure gives each soloist freedom to shape their statements without the constraints of repeated chord patterns. Shorter opens with an extended tenor saxophone solo, his lines weaving through the open harmonic landscape with exploratory intensity. Hancock follows with a piano solo that reflects his deep understanding of his own composition's harmonic implications. Bassist Reggie Workman then contributes a solo that demonstrates the instrument's potential for melodic improvisation at fast tempos. Drummer Joe Chambers closes with a drums solo that caps the performance with rhythmic fireworks. The track represents the most harmonically adventurous moment on the album, pointing toward the freer approaches that both Shorter and Hancock would explore in subsequent decades. Hancock's composition provides a skeletal framework that encourages spontaneous interaction rather than structured blowing, presaging the open-form jazz that would emerge in the late 1960s.
