Niagara Moon is Thomas Erwin + other collaborators, most notably his singing partner Huimin Wan.

Specializing in mellow, lushly produced indie-pop songs that combine the intricate melodies of Pet Sounds and Sgt. Peppers with the 21st century style of artists like Of Montreal and Belle & Sebastian, Niagara Moon's sound is often whimsical, sardonic, and mildly psychedelic.
Formed during a three-year period of living in Kyoto, Japan, the name itself is inspired by 70's Japanese songwriter Eiichi Ohtaki.  

"Thomas Erwin’s project Niagara Moon expands on musical trends of the past by folding in lessons and technology of the present. “Bad Vibes” sounds like a track from a hypothetical album by the Beach Boys’ Brian Wilson responding to the Beatles’ Sgt. Pepper. The melodies and feelings of those ’60s powerhouses remain, but with a modern indie rock sensibility and pulled together with modern electronic production." - Daniel J. Willis, Riff Magazine
