You're all wrong, WRONG! Gah.

Just a quick note on versatility in producers, it has been put to me that producers are sought out for their signature sound and that if you were to employ a producer with a signature sound, getting a product with someone else's signature sound might cause some dissatisfaction, not to mention accusations of infringing copyright. I am of the opinion that, while this may be true of the really big, famous producers, on a local scale, having your own signature sound and sticking rigidly to it is not necessarily going to get you very far. In the defence of versatility, your signature sound will be at its most unique if it has evolved from a mastery of a variety of different styles of sound engineering.
