Moon Letters is a prog rock band, formed in Seattle, USA in 2016. Their debut album, Until They Feel the Sun, with renowned producer Barrett Jones (Foo Fighters), garnered positive reviews internationally. The album was released at the Seaprog festival in 2019 and immediately placed Moon Letters in the vanguard of the new wave of American progressive rock.

Their second album, Thank You From the Future, produced in Seattle by Robert Cheek (Band of Horses), was released in late 2022 and has been embraced by prog fans and reviewers. 2023-24 found the band touring North America, including: Terra Incognita Fest in Quebec City, ProgDay Fest in North Carolina, and Prog on the Ranch in Florida.  

​

Their third album, This Dark Earth was released in 2025 (again with Cheek) on June 13th, as part of Seaprog / Cascadence Festival in Seattle.  It was followed by their first tour of Europe, including ArtRock Fest in Sweden, and concerts in: France, Prague, and the UK.  During completion of the album, bassist/vocalist Mike Murphy relocated to the east coast, and Curtis Parker (Witch Ripper) has stepped in.  2026 has seen the band return to Prog on the Ranch Festival, as well as opening for acts such as WitchCraft (Sweden).
