UMUR "Hall of Mirrors" is the 4th full-length studio album by Greek technical/progressive death/thrash metal act Acid Death. The album was released through 7Hard Records in September 2015. It´s the successor to "Eidolon" from 2012 although the two full-length releases are bridged by the 2013 "MisleD 2013 Re-recorded" EP. There has been one lineup change since "Eidolon (2012)" as guitarist Kostas Karavelas has been replaced by John Anagnostou.

Stylistically the material on "Hall of Mirrors" continue in the same technical/progressive death metal direction as the material on "Eidolon (2012)". It´s music strongly influenced by the early 90s technical/progressive death metal scene (artists like Death and especially the Italian Sadist come to mind). It´s a bit more contemporary sounding though, which means it´s a little more heavy and groove oriented than the 90s influences. The title track is for example a full fledged groove metal track.

"Hall of Mirrors" features a well sounding production job, tight and skilled musicianship, and the material is well written and effective. The combination of 90s technical/progressive death metal elements and more contemporary heavy groove metal oriented elements won´t please all listeners, but there´s nothing wrong with the execution or the overall album package. This is a quality release and a 3.5 star (70%) rating is deserved.
