There have been quite a lot of bands that have gone on to form another band after a fallout with the lead singer or the lead singer quitting.
Some bands, such as Alter Bridge and Velvet Revolver, have been formed by the band members of their older bands, Creed and Guns N' Roses in this case. I know that a lot of these original bands normally do seemingly better than the newer ones but I find myself actually preferring the new ones in many cases.
Although a lot of bands that either separate from the singer or form with new members don't always do so well, Guns N' Roses and Velvet Revolver are strongly Slash based; Creed and Alter Bridge being quite based on Mark Tremonti's amazing guitar playing too.
On the other hand, as well as the bands going on to be more successful, sometimes the lead singer in fact has an impressive solo career. I don't know about a lot of TDG (Three Days Grace) fans but I have been listening a lot to Adam Gontier's solo material and I believe that he could possibly go on to do better than TDG, if he never decides to rejoin them. But occasionally the careers of the old band members doesn't go as planned. Axl Rose of Guns N' Roses has seemingly lost a lot of fans and followers to the original GNR fanbase.
I have to say that I wrote this to see if the fans of bands such as these share the same opinions as me. But as well as to see this, I did this to see the overall opinion and view of when bands do this. So yeah, what do you guys think? Please leave comments and possibly get a discussion going on this.
