Miserere Luminis' third album, Sidera, is a captivating journey through lush atmospheres and profound emotions. The Montreal trio's reemergence after a 14-year hiatus is a triumph, delivering an album that is both a continuation of their mature compositions and a departure from the darkness of their second wave-informed black metal roots. The album's production wisely highlights the strings and piano, creating a rich and vibrant soundscape that is both familiar and fresh. However, the album's length and uniformity may leave some listeners wanting more variety and breakout moments. Despite this, Sidera is a powerful and captivating listen, offering a glimpse into the future possibilities of Miserere Luminis' music. In my opinion, the album is a solid addition to the atmospheric black metal genre, but it may not be a game-changer for the genre as a whole. The album's strength lies in its ability to transport listeners through its dense and glamorized soundscapes, even if it lacks the diversity and breakout moments that some listeners may desire. Overall, Sidera is a must-listen for fans of the genre, and I look forward to seeing what Miserere Luminis does next.
