Its because most of the members (i think 5 out of the 9 members)had side projects to work on.Like the lead singer Corey Taylor and guitarist Jim Root were working on there original band Stone Sour.The Drummer Joey Jordison and the percussionist Clown made Murderdolls with people from other bands.Thats why theyre breking up again.Because Stone Sour's comin up with a new album.They have a hit called 30/30.150 and Reborn.Stone Sour formed in 1992.Theyre songs on their cd have been around for about 5-10 years now.Murderdolls was formed in 2002 with one cd.Thats the reason why Slipknot keeps breakin up.Their members got to work on their other bands.
