Giant Steps, released in 1960 on Atlantic Records, is the fifth studio album by jazz musician John Coltrane as band leader. His first album for the Atlantic record label was a breakthrough for Coltrane, with many of its tracks soon becoming practice templates for jazz saxophonists. In 2004, it was one of only fifty recordings chosen by the Library of Congress to be added to the National Recording Registry.
This recording exemplifies Coltrane's melodic phrasing that came to be known as sheets of sound, and features his explorations into third-related chord movements became known as Coltrane changes. Jazz musicians continue to use the Giant Steps chord progression, which consists of a peculiar set of chords that often move in thirds, as a practice piece and gateway into modern jazz improvisation. 
Happy to select Giant Steps for an album cover redesign. It was my first Coltrane purchase, but definitely not my last.
