The guy with all the connections. The guy who finds an artist, shells out the money for the recording, promotes and cashes in on the earnings. The guy who lives in the mansion with a ferrari. An example of a producer is Ross Robinson, the guy who produced Korn, Slipknot, Glassjaw, Limp Bizkit, and a bunch of other famous rock bands. Just like a movie producer, he has all the funds, all the smarts, and not necissarily any of the talent.
