72826 was recorded in Maynard James Keenan's rehearsal room, on a 4-track recorder. It features early versions of songs that reappeared in their later releases: "Cold and Ugly", "Hush", "Part of Me" and "Jerk-Off" on Opiate, and "Crawl Away" and "Sober" on Undertow.
72826 features six tracks. Two of them, "Cold and Ugly" and "Jerk-Off", were never released as studio recordings outside this demo. Instead, they were re-recorded live at the Jello Loft on New Year's Eve 1991. The live recordings were featured on the band's next EP, Opiate.
