20th studio album by the German heavy metal band formed by vocalist and bassist Mat Sinner. The heavy metal world has produced quite a few legends. But none is like Mat Sinner. So much conviction, lifeblood and self-sacrifice, so much pure heavy metal spirit, so much dedication is usually not found bundled in a single person. Since 1982 he fronts the band named after him, with which he now triumphantly returns in the form of "Brotherhood": a massive album, whose title is as self-explanatory as the mission of its creator. Self-produced and mixed/mastered by Jacob Hansen (VOLBEAT, among others), it is a record that carries the band's internal brotherhood under its heart as much as the brotherhood of the worldwide heavy metal following.
