Although this looks like a set of trainees at a mechanics, or the cast of a 1980s coming of age movie, this is in fact arguably the most accomplished heavy metal band who ever lived. Yes, folks, this is Metallica. The clue is James Hetfield over there on the right of the picture, making the cardinal sin of wearing his own band's t-shirt.
Taken in 1985, when the band were still experimenting with their sound and their hairstyles, this captures them in the pomp of their youth, raw and unexposed. A year later they would release 'Master of Puppets' and begin to make waves and change beyond all recognition. Note how pleased with himself Lars Ulrich looks, hugging his own arm there in the middle. He's probably thinking about how he'll go on to be instrumental in bringing down Napster.
