...I think of improvising as composing - fo me it's all about playing melodies. When I improvise, there's not a lot of real thinking going on, per se - it's more like riding a wave. and I know how to stand on the board

I do believe it's possible to play a lot without overplaying. It's when a musician becomes too self-centred that it becomes problematic. You need to be aware of how what you're doing is affecting everyone else, and that's something young musicians often forget. Playing in a band is a shared experience. It's about what everyone is doing together.

I think a lot of the more successful artists of our time basically have barracudas for managers

... don't be afraid to screw up !... one of the key issues to learning is making mistakes ... if you're not making mistakes, you're probably not having a very good time

I don't find a lot of people actually saying things through music any longer. They are not trying to say anything with their music, they just want to make money with it. I think it's important to actually say something real, something meaningful, rather than just write some trash and try to sell it.
