UMUR "Transmissions of Chaos" is a split release by US technical thrash metal act Vektor and Dutch technical thrash metal act Cryptosis. The split was released through District 19 in February 2021. It features 4 tracks and a total playing time of 20:03 minutes. Vektor are well known as one of the more prolific contemporary technical thrash metal acts and the two new Vektor tracks on "Transmissions of Chaos" actually mark a return to the scene after a longer recording hiatus following the release of "Terminal Redux (2016)" (the band´s third full-length studio album). Cryptosis on the other hand are a less known acquaintance having only released a couple of singles by February 2021. Two of the single tracks make up their contributions to "Transmissions of Chaos". They would release their debut full-length studio album "Bionic Swarm" in March 2021. They did however work under the Distillator monicker in the years 2013-2020 playing a more regular type of thrash metal and releasing a couple of studio albums under that monicker, so these guys are also pretty seasoned musicians/composers.

Vektor open the split with their two tracks "Activate" and "Dead by Dawn", and it´s immediately audible that Vektor have changed and developed their style and sound a lot in the years since "Terminal Redux (2016)". They still play their own brand of technical thrash metal (sci-fi themed and Voivod influenced), but lead vocalist/guitarist David DiSanto has opted for a different singing style to his usual high pitched screaming, and now performs more regular snarling thrash metal vocals. But as a new thing in the world of Vektor he now also performs melodic clean vocals (on "Dead by Dawn"), and the new vocal approach provides Vektor with a few more weapons for their arsenal and dare I say a more accessible sound.

The two Cryptosis tracks "Decypher" and "Prospect of Immortality" aren´t far from the Vektor tracks in terms of sound and style. Cryptosis also play a sci-fi themed technical thrash metal style with progressive elements and it was definitely a smart move by the Austrian District 19 label/management company to promote newcomers Cryptosis on this split with the more well known Vektor. Upon conclusion "Transmissions of Chaos" is a high quality split release featuring strong compositions and stellar performances from both acts, and fans of technical/progressive thrash metal should take note here. A 4 star (80%) rating is deserved.
