KISS, Aerosmith, Metallica, Bon Jovi, Van Halen, GnR, Rolling Stones, Pink Floyd, Megadeth, shit I could go on all day.........I don't know if it's true but I heard before his death, Kurt Cobain had a 90% share of the profits and ownership in Nirvana.
I know most bands are like that, but that doesn't make it right. You bust your ass off for years and suffer right alongside your bandmates to make it, then some bandmate decides he's more important than the rest of the band and gets a larger cut and starts bossing everyone else around.
