On Street's Disciple, Nas finally was able to release a double disk (refer to I Am...). Nas left Columbia and joined Def Jam to make some of his most ambitious concepts such as risking is reputation to pronounce Hip Hop Is Dead and address racism with his untitled (Nigger) album - Nas was hinting to proceed with some of his controversial concepts on Street's Disciple. Columbia subsequently released a Greatest Hits of Nas and "Ether" was mysteriously absent on the track listing - possibly due to the fact that Jay-Z and Nas mended ties on the Def Jam label.
