UMUR "The Great Burst of Light" is the debut full-length studio album by US, Texas based post-metal/progressive death-doom metal act AEGOS. The album was independently released in April 2021. AEGOS formed in 2021, released "The Great Burst of Light", and "The Current" single in November 2021 before changing their name to Stillbeing in 2022.

The album features 5 tracks and a total playing time of 48:44 minutes. All tracks are at least 6 minutes long, and four of them are around 10 minutes long. It´s slow building, atmospheric, and very heavy post-metal/doom metal with both male- and female clean singing and death metal growling (courtesy of Jei Doublerice from Despite Exile, Abiogenesis). The songs are quite adventurous in sound, structure, and style, and they move through several different timbres, dynamics, and moods. A good example is "Qualia" which features both female singing and saxophone playing on top of a heavy doom metal bottom and a cold almost epic black metal styled atmosphere. "Gravity Bending Light" is another example of the eclectic nature of AEGOS music, as it features a longer middle section featuring cello, which provides that part of the track with an almost chamber like (classical music) atmosphere.

The sound production is powerful, heavy, and detailed, and upon conclusion "The Great Burst of Light" is a good quality debut release by AEGOS. It´s an album for those who crave a little more than just heavy riffs and rhythms when listening to doom metal, and if you prefer a more creative and eclectic take on the genre, this album certainly applies. A 3.5 star (70%) rating is deserved.
