'Crowz' will sadly never see the light of day, and a quote by Mick Thomson himself, "Crowz never existed". Crowz is believed to be a Bootleg made of Rare Slipknot demos which were never put together into a record. Most songs would be re-made and featured on MFKR and Slipknot.
"Crowz" was recorded, and re-recorded, and re-recorded... Before Slipknot got signed they were working on a "revised" MFKR with better produced versions of those songs, along with newer stuff that was written with Corey Taylor on vocals, This was to do two things:
1) Give them a quality demo to shop to labels.
2) If not signed, they could put it out independently as a replacement for MFKR.
Some of this stuff was recorded at SR with Sean McMahon, some was done at Juniors' Motel in Otho. It really depended on what was needed at the time. Some of those songs have many multiple versions and mixes. For example, there are at least two versions of 'Prosthetics' that I have heard prior to the Self-Titled album. Some songs, like Snap, were done quickly at Otho and sent out as a demo to give record companies something new compared to MFKR.
Crowz refers to a saying we (Slipknot) started which started following a spooky incident when we where taking Paul Gray home after a studio session, and the road his place was on was covered entirely with crowz, or blackbirds, or whatever. Thousands upon thousands of them. When the headlights flashed over them, they all took to the trees as one big, black mass. It was eerie. Then, they all sat in the trees and phone lines watching us. That's where Crowz came from. Plus, Shawn found a dead one in his driveway, and kept it in a big, commercial pickle jar, and carried it around at shows until it turned to mush, During shows Shawn would open the jar, this would cause him to vomit all over the place and also cause fans to start vomiting all over the place. It was (sic), it was kept in the jar with all the bacteria and flesh eating creatures. It started secreting this brown liquid and became a fine sauce. [yum] Some kids broke the jar open and played catch with it for awhile and now it's disposed.
