Кто был двумя первыми, не знаю еще...
Nuclear Blast was formed in 1987 after founder Markus Staiger travelled throughout the United States for four weeks and saw a gig of his favorite band BL'AST!. The label was originally titled simply "Blast", but this was soon changed to Nuclear Blast. The label's first release was a vinyl compilation called Senseless Death (NB 001) featuring US Hardcore bands like Attitude, Sacred Denial, Impulse Manslaughter and others. The first edition of 1000 copies was sold out after one year.
