The free jazz movement received its biggest impetus when Coleman moved from the west coast to New York City and was signed to Atlantic. Albums such as "The Shape of Jazz to Come" and "Change of the Century" marked a radical step beyond his more conventional early work. On these albums, he strayed from the tonal basis that formed the lines of his earlier albums and began truly examining the possibilities of atonal improvisation. The most important recording to the free jazz movement from Coleman during this era, however, came with "", recorded in A&R Studios in New York in 1960. It marked an abrupt departure from the highly structured compositions of his past. Recorded with a double quartet separated into left and right channels, "Free Jazz" brought a more aggressive, cacophonous texture to Coleman's work, and the record's title would provide the name for the nascent free jazz movement.
