The Apostasy is the eighth full-length album by Polish extreme metal band Behemoth. Unlike Behemoth's previous studio albums, a piano and a horn section (a trio of trumpet, trombone, French horn) were used in several of the album's songs. During the recording sessions, the band re-recorded a new version of quot;Chant for Eschaton 2000quot; - originally released on their album Satanica - which was released on the band's 2008 EP, Ezkaton. The Apostasy is Behemoth's first album to chart on the Billboard 200, having debuted at #149.
