Wow. There are fake musician LEGO minifigs! They don't so much have names as occupations, but what can you do. Punk Rocker is from Series 4, set 8804 LEGO Minifigures. He comes with a slick flying V guitar with is really more 1950s/1960s than punk, but whatever.
From his online bio at LEGO.com:
There are all kinds of legends about the noisy Punk Rocker. Some say that he used to be shy and quiet until he got hit by a bolt of lightning one day. Some say that he’s sworn never to stop rocking until his music has created world peace. But whatever you may believe, one thing that everybody has to agree on is that the Punk Rocker is very, very, very LOUD!
