This "demo" was launched through 1996 before Slipknots self titled album debut album. A limited amount of copies were released so this demo is extremely rare and is unavailable to buy in shops, so try ebay. Obiously beware of FAKES! This demo included two of possibly Slipknot's most successful songs to date, Spit It Out and Wait and Bleed.
Each song on this demo was later re-used later on. They appeared either on an album (even if they were exclusive to a special edition), or a soundtrack.
The lyrics in "Despise" were later re-used in the song "Purity".
