Thank you so much for all the answers!
I play rather agressive (which is not always a good thing), I think the manager and the producer were trying to have a more mellow sound.
I'm new in this band, they have been playing for some time now and the original bassist quit because he didn't want to be in such a serious project, he didn't want to earn a living as a musician, he just wanted to keep music as a hobby. He was really honest about it and there are no grudges.
Anyway they asked me to join knowing I have a serious attitude and that I always thought of bands as a job and everything that implies (being on time, rested, fed, with energy to work, etc).
I'm still gaining my place, so if they ask me to record with the Jazz, i'll do exactly that. Im just happy to have landed a spot between people so comitted.
Thank you very much everyone!
