"This was something else. I could feel it in every part of me." What it was like seeing metal legends Metallica in their early days, according to fellow thrash veteran and Death Angel frontman Mark Osegueda

Metallica in 1986.

This year marks 40 years of Metallica's groundbreaking, genre-defining third album Master Of Puppets. It was a record that confirmed the Four Horsemen as the most exciting, boundary-breaking band to have emerged from the storied Bay Area thrash metal scene, and four decades on, its legacy and influence remain as strong as ever.

Speaking in the new issue of Metal Hammer, Mark Osegueda, frontman of fellow Bay Area veterans Death Angel, speaks warmly of hearing Master Of Puppets for the first time and seeing Metallica live during their early days.
