UMUR "Dimensions" is the 3rd full-length studio album by US technical/progressive thrash metal act Believer. It would also be their last album in 16 years as Believer disbanded in 1994 and wouldn´t release their next album "Gabriel" before 2009. The album was distributed by R.E.X. Records for the christian market (Believer write lyrics based on their christian beliefs) while Roadrunner Records distributed the album to the secular audience. "Dimensions" was re-released by Retroactive Records in December 2004 with 3 bonus tracks which were recorded live on the 31th of October 1989. The re-release is limited to 1000 copies. A few lineup changes have taken place since the release of their last album "Sanity Obscure (1990)" as guitarist Dave Baddorf and bassist Wyatt Robertson have left the band and Jim Winters has replaced them and handles both the bass and some of the guitars on "Dimensions". The core of the band, guitarist/lead vocalist Kurt Bachman and drummer Joey Daub are still present in the lineup.

The basis in the music on "Dimensions" is still aggressive technical thrash metal like Believer also played on their two previous albums but the music on "Dimensions" is far more sophisticated and varied than the case was on the predecessors. Believer venture into progressive territory more than once during the playing time and listeners who found their previous albums too simple should try this one out. There are lots of interesting time signature changes, samples, female soprano vocals and a far more integrated use of orchestral string arrangements on this one than what we´re used to from the band. The pace is generally a bit slower than the predominanly frantic pace of their earlier releases but there are still very fast paced sections on the album. The string arrangements are heard on "What is but cannot not be" but are fully integrated in the four chapter 20 minutes long suite (the songs are seperated. This is not one long track) "Trilogy of Knowledge". A powerful mix of technical thrash metal and classical string arrangements with both aggressive raspy vocals and female soprano vocal parts. This is the centerpiece, highlight, and the most progressive moment of the album. The other tracks on the album are quality material too.

The musicianship are on a high level throughout. Challenging compositional structures and tight playing make "Dimensions" an intriguing listening experience. The sound production by The Trauma Team (Kurt Bachman and Joey Daub) and Ted Hermanson is dark and powerful. An excellent sound that suits the music well. While Believer never received the attention they deserved I personally think "Dimensions" is a seminal technical/progressive thrash metal album from the 90s and mandatory listening if you´re a fan of the style. A 4 star (80%) rating is deserved.
