I was watching some of Bruce Dickinson's Anthology DVD the other day. I remember buying "Tattooed Millionaire" when it came out and I gave it away after a few listens because I didn't like it. I think that I heard "Balls to Picasso" once when it came out and it was okay. Most of the music on the DVD was alright, but not as good as I had hoped. I know his later albums got better reviews, but I have not heard them. Rob Halford was another one where I couldn't get into his post Priest stuff. Fight were okay and the Halford stuff was better, but none of it was as good as I had hoped and nowhere near as good as Priest's Painkiller. I think it's hard for a singer of an established band to leave and do something that's just as good as the previous band's work. There are some who have done it or come close. When Ozzy left Sabbath very few people thought he would do much. He did two great albums right off the bat and some decent ones later on. Although he was just about always surrounded by good musicians and he had a lot of help. Ronnie James Dio had success with Rainbow and Black Sabbath, but left and formed his own band because he wanted to call the shots. The 80's was a good decade for Dio and the 90's were a little rough on him. When Mercyful Fate broke up King Diamond changed the music and his voice a little and had some real success in the late 80's. David Lee Roth had a supergroup for a limited time and some real success for his first two releases. In the cases of Dio and King Diamond, they both started with at least a couple of people in their band that they had played with before so that probably helped. I guess it can be so hard for someone going solo because there is likely be a set of expectations placed on them by fans of their prior band. You probably don't want a singer to completely change their style. At the same time it's pointless to do something like sound just like your prior band like Vince Neil did on his "Exposed" album. Then people wonder "why leave if you're going to do the same exact thing?". Most of the people I mentioned above eventually went back with their previous band for at least a while as well. I guess a lot of musicians like to be in charge, but ultimately they do what they have to in order to make a living.
