siLLy puPPy After a near decade absence after their 2006 album “Death Of A Dead Day,” the English progressive metalcore outfit SIKTH dropped a little EP out as an appetizer to keep their fans salivating for yet another full album. Despite only having released two full-length albums, OPACITIES is actually the fourth EP following the twin EP output of 2002 and the 2006 release “Flogging The Horses.” The band members are exactly the same as their previous lineup, so this is very much a genuine SIKTH release and once again the band delivers an outstanding cross-pollination of hard and heavy metalcore fused with their brand of extreme progressive metal that often reminds me of the type Enslaved weaved into their albums such as “RIITIIR.” OPACITIES is a short but sweet EP with six tracks not quite reaching the half hour mark.

OPACITIES pretty much continues the well-known style that SIKTH unleashed on their full-length albums, that being highly caustic core type riffing mixed with progressive song structures. While on the full albums Mikee Goodman utilized his frenetic screaming vocal effect as his main sonic instrument of torture, on this one there is a lot more emphasis on clean vocal delivers. The opening tracks “Behind The Doors,” “Philistine Philosophies” and “Under The Weeping Moon” are the most recognizable SIKTH tracks sounding very much like the noisiest and obnoxious tracks heard on the earlier albums, however the core elements are somewhat toned down and progressive metal riffing is just as and often more prevalent and sometimes it actually sounds more akin to heavy alternative metal styled riffs.

The biggest surprises are the spoken word “Tokyo Lights” which utilizes a poetic approach along with vocalized shadow and sound effects to create a very memorable and bizarre track. With no instruments to be heard. “Walking Shadows” returns with the full furry of progressive core riffing and metal intensity including some trademark frenetic vocals akin to the opening tracks but “Days Are Dreamed” completely changes things up with an etheric atmosphere that introduces a clean vocal track that is not metal at all but rather a progressive rock composition that will probably remind more of the newer Opeth albums than of earlier Sikth releases as the mood is thick and the symphonic touches dominate.

OPACITIES is a quirky little mix of old and new for SIKTH but still manages to deliver a satisfying shot of their unique hybridization of progressive rock, metal and the core elements that they belt out with all the technical precision one would expect. This band has maintained a very high standard and is fairly consistent from one release to another and in that regard OPACITIES will not disappoint especially if you can appreciate the diversity of styles as heard on albums such as “The Trees Are Dead & Dried Out Wait For Something Wild.” This EP rekindles the past but also points to newer directions that the band could possibly carve out and expand on future releases, so it is indeed a satisfying whetting of the appetite for fans to anticipate.
