History will undoubtedly enshrine this disc as a watershed the likes of which may never truly be appreciated. Giant Steps bore the double-edged sword of furthering the cause of the music as well as delivering it to an increasingly mainstream audience. Although this was John Coltrane's debut for Atlantic, he was concurrently performing and recording with Miles Davis. Within the space of less than three weeks, Coltrane would complete his work with Davis and company on another genre-defining disc, Kind of Blue, before commencing his efforts on this one. Coltrane (tenor sax) is flanked by essentially two different trios.
