Used By Permission. But a good review is worth its weight in gold. This may sound like it's too obvious to mention, but trust me - if you contact a potential reviewer by demanding their submissions address because you are simply the best thing that has happened to music since the microphone and the reviewer would be out of his or her mind to pass you up, you're likely to be disappointed at the response you receive. Sure, every artist deserves a chance. But you're biasing a reviewer against you right from the start if you use that tactic.
Reviewers despise being taken for granted.
Your initial contact should be polite and brief. You don't want to know how much spam e-mail I receive in a day and messages like that simply make me feel as if I'm being asked to check out the latest in cheesy porn. I delete such messages on sight and I honestly don't know many reviewers who pay them any attention either. Pictures are nice but they don't really matter as far as most publications are concerned. If a publication requires further material, you'll be contacted for it.
