Sonus Umbra

Sonus Umbra is a Chicago-based progressive rock collective that's been crafting intricate, thought-provoking music since forming in the late 1990s. Originally founded by Mexican-born bassist/composer Luis Nasser after relocating to Illinois, the band (whose name translates to "Sound of Shadow") blends dark, theatrical elements with complex arrangements, channeling influences from classic prog acts while maintaining a modern edge. Their recent serialized releases like the multi-part *Whiteout* and *Insects* series showcase their penchant for conceptual storytelling, pairing angular riffs and shifting time signatures with existential lyrics exploring human nature and societal issues.

Known for their collaborative spirit, Sonus Umbra operates as a rotating ensemble of musicians, with longtime members like guitarist Jeff Laramee contributing to their signature mix of metallic intensity and art-rock sophistication. Tracks like *Scream* and *Snapshots From Limbo* highlight their dynamic range, veering from pummeling rhythms to melancholic melodies. While maintaining a DIY ethos, they've cultivated a dedicated following among prog enthusiasts who appreciate their willingness to tackle unconventional themes – from AI ethics to personal alienation – without losing their sense of musical playfulness.
