Miles Smiles is an album recorded in October 1966 by the Miles Davis quintet. On three tracks from this album ("Orbits", "Dolores",
"Gingerbread Boy"), pianist Herbie Hancock takes the unusual step of dispensing with left-hand chords and playing only right-hand
lines. Somewhat unusually for this group, the album includes two compositions not written by members of the group. Both are
treated far more freely and loosely than the original versions.
