Seymour Stein has to be one of the most interesting people in the music business. He got his start in the industry at 14 (!), was still a teenager when he worked for Billboard, and went on later to found Sire Records. The iconic yellow label with the big S was a familiar sight on my turntable growing up; he signed the Ramones before anyone knew what punk rock was (Stein disliked the description), and later Talking Heads. And others you may know: the Smiths, the Cure, the Pretenders and some aspiring dancer named Madonna. He's now in his 70s, but still in the business.
