UMUR "Gruesome Acts of a Deranged Mind" is the debut full-length studio album by UK goregrind act Organic Brain Disorder. The album was released through Bizarre Leprous Production in October 2023 and reissued by Acid Redux Productions in April 2024. Organic Brain Disorder is a one-man project with Brazilian born, but UK based Corvo handling all instruments, drum programming, and vocals. Organic Brain Disorder released a demo (titled "Demo 2023") in August 2023, but other than that, this is the first release by Organic Brain Disorder.

Stylistically you get a filthy, fast-paced, yet sharp and clear sounding goregrind style on this eleven tracks, 16:01 minutes long album. The vocals are low-in-the-mix distorted growling, which have that nasty juicy quality to them, which many goregrind bands favor. There´s a strong harcore/punk influence heard, and sometimes I´m reminded of early Napalm Death. At least when it comes to the instrumental part of the music. The drums are programmed, and Corvo has done a decent job with the programming. The sound production is powerful too, and "Gruesome Acts of a Deranged Mind" is overall a well produced release.

Upon conclusion you won´t hear anything on "Gruesome Acts of a Deranged Mind" which you haven´t heard before. So innovation and uniqeness are not features found here. But if you enjoy the goregrind style you could definitely spend you money worse than on this album. A 3 star (60%) rating is warranted.
