CD reissue. Cracked Brain is the fourth full-length studio album by German thrash metal band Destruction, released in 1990. It is the band’s only album to feature André Grieder of Poltergeist, replacing Schmier, who was fired after the initial sessions for the album. Also featured is a cover of The Knack song “My Sharona”. Destruction formed in 1982. They are often credited as one of the Big 4 of the German thrash metal scene, the others being Kreator, Sodom and Tankard. In addition to helping pioneer black metal by containing several elements of what was to become the genre, Destruction was part of the second wave of thrash metal in the late 1980s, along with American bands Testament, Sacred Reich, Death Angel and Dark Angel.
