The wonderful Post-Bop album Miles Smiles (1967) was recorded by Davis’s second great quintet, which featured saxophonist Wayne Shorter, pianist Herbie Hancock, bassist Ron Carter, and drummer Tony Williams. The album showcases Davis’ deeper exploration of modal performance with looser forms, tempos, and meters. Although it did not follow the conventions of Bop, the album did not follow the formlessness of Free Jazz.
