Saying farewell to bebop, "Giant Steps" was Coltrane's second album to be recorded for the Atlantic label, and marked the first time that all of the pieces on a recording had been composed by him. The recording exemplifies Coltrane's melodic phrasing that came to be known as 'sheets of sound', and features the use of a new harmonic concept later to be known as 'Coltrane changes'. The set features early versionss of "Naima", "Cousin Mary", "Mr PC", "Spiral", and "Syeeda's Song Flute".
