Mono are a instrumental post-rock group from Tokyo Japan made up by four members: Tamaki, Takaakira Goto, Yoda and Yasunori Takada
Mono sounds a bit like Instrumental Sigur-Rós and Mogwai. Their music is full of intense emotions, with the highest of highs and the darkest of lows. Their songs build with waves of crashing cymbals over consistant drums, then exploding with hard hitting electric guitars that leave you in awe.
On their way to folding one thousand paper cranes for humanity they released their latest album "You Are There" in late 2005. The album was produced by Steve Albini, famous for his recording techniques and has produced albums for bands such as: Pixies, Breeders, Nirvana, PJ Harvey, Smog, Low, Will Oldham and Mogwai (to name a few).
I highly recommend downloading some mp3s and checking this band out for your self!
