Sonus Umbra
We are a progressive rock band, established in Mexico City back in the 20th century. We broke up, regrouped and operated from the late 90's to the mid 00's in Baltimore, broke up again and reformed in Chicago where we have been fully functional since 2013, albeit geographically dispersed between Chicago, Louisvillem Mexico City and Abu Dhabi.
Bassist/composer/ringleader Luis Nasser is the founder and only member who has appeared in every incarnation of SONUS UMBRA. We have toured across North America, from Mexico to Canada, and played in numerous progrock festivals.
This year we played our first show in the UK at the Fusion Music Festival, 2026, and we couldn't be happier to return to Progday. Our new album Liminality will be available early October. If you want to hear shadows made of sound, we invite you to join us online, take the great fall inwards and listen.

"BEYOND THE PANOPTICON is not an easy and superficial musical experience! Au contraire, it's a marvelous musical journey... very cinematic and rich in audio images,we are invited for a fantastic, transcedental journey and in the end,we have the feeling of being a part of a great musical endeavour!"
- Oviviu, PROGARCHIVES
"[Winter Soulstice]... Highly recommended to prog fans who like a good balance of melody and complexity. "
- PROGSPHERE
"They’re unlike any other band, and that’s a refreshing thing. Highly recommended!!"

"For me [Winter Soulstice] is one of the best albums I have heard in 2013 and I hope it gets the recognition that it deserves."
