The End of Sanctuary originally came out in March 2000 on Nuclear Blast and is an album by the German heavy metal band Sinner, led by singer and bassist Mat Sinner. The lineup at the time included guitarists Alex Beyrodt and Henny Wolter, keyboardist Frank Rössler and drummer Uli Kusch, known from Helloween. The album contains twelve tracks and was produced by Mat Sinner at House of Music Studios. Musically the band opted for a more traditionally oriented heavy metal sound, heavier than its earlier, more melodic hard rock work.
