About pushing him... maybe with this kind of musicians MK is more open to be pushed because as proffesional they are, they would only push him if it´s needed, so probably MK will accept it, but when in a band where everybody think they have a say, pusing would be more frequently and could generate some conflicts. With his actual band, they know what that their duty is to play for the artist, so they will only suggest something when they have to, or are asked to...
That´s the reason why most of the artists that were succesful in a band go solo, and that's why makes me wonder why, if they kind of knew they wanted to be the leaders, they started a band instead or started a individual career with a bunch of musicians.
