I found over the years there are basically two kinds of producers. The ones that micro manage and those that let the music develope.

The most micro managed was a producer that after a linear play through of my part then took a full day of me redoing that part over and over again a section at a time. Sometimes doing a three or four note riff over and over till he got exactly the sound he was looking for. The other producer just had me do three takes and said he'd work with them. (He liked the first take and just wanted something else if needed)

While the first producer was exasperating to work with, he had worked with Streisand so perfectionism was his mantra.
