Mono are a post-rock group from Tokyo, Japan formed in 1999. The songs, all of which are instrumental, are usually focused on layered guitar melodies. Strings and pianos are also prominently featured in some songs. They are known for their powerful live shows and their complex guitar work.
The band's style of instrumental rock music is influenced by the genres of experimental rock and shoegazing, as well as by both the classical and contemporary classical periods of classical music, and also by noise and minimalism. Mono's sound is characterised by the lead and rhythm guitars of Goto and Yoda respectively, both of whom make extensive use of reverb, distortion and delay effects. The band's live performances are noted for their intensity, both in the playing and in the dynamics.
The video below is a (brilliant) performance of 'Ashes In The Snow' recorded on the bands 10th anniversary at the NY Society For Ethical Culture in Manhattan on May 8th 2009.
'New York Soundtracks' is actually a compilation album with various artists performing a selection of Mono's songs, but the release was credited as Mono's.
