UMUR "Expurse of Sodomy" is an EP release by German thrash metal act Sodom. The EP was released through Steamhammer Records in March 1987 and bridges the gap between the band´s debut and sophomore studio albums "Obsessed by Cruelty (1986)" and "Persecution Mania (1987)". The material from the EP are included as bonus tracks on the original European CD version of "Persecution Mania (1987)", and on later re-releases of said album. At the time of original release, the 3 track, 14:50 minutes long EP worked as a teaser release for the album release of "Persecution Mania (1987)" later the same year.

Stylistically "Expurse of Sodomy" is also closer in style to the raw an aggressive thrash metal style on "Persecution Mania (1987)", than to the proto-black/speed/thrash metal sound of "Obsessed by Cruelty (1986)". The sound production is raw and powerful, yet detailed and well sounding and the addition of guitarist Frank Blackfire to the lineup (he replaces Destructor) has meant a lift in quality of the musicianship and songwriting. These guys can play and they can also write an effectful thrash metal tune.

As a consequence of the material from the EP being included on most versions of "Persecution Mania (1987)", the relevance of "Expurse of Sodomy" as an individual release has decreased over the years, but upon original release it was an EP showing great musical progress compared to the early releases by the band. It´s definitely a successful bridge builder between the early releases and the band´s future sound, and more importantly it´s a good quality release deserving a 3.5 star (70%) rating.
