8 artists sharing the name Mono

Mono’s Biography Ironically, there are eight artists sharing the name Mono;

Japanese: Mono are a post-rock group from Tokyo, Japan. The songs, all of which are instrumental, are usually focused on layered guitar melodies. Strings and pianos are also prominently featured in some songs. Mono are known for their powerful live shows and their complex guitar work. Their first EP, titled “Hey, you” appeared in September, 2000. So far, they have released four full albums: “Under The Pipal Tree”, “One Step More And You Die”, “Walking cloud and deep red sky, Flag fluttered and the sun shined” and “You Are There”. They also have several other records, including a remix album, a collaborative split record with Pelican, an album collaborating with World’s end girlfriend and another EP, titled “Memorie dal Futuro”.

British: Mono were a British pop duo which became a one-hit wonder in the late 1990s with their song “Life in Mono”. The group is considered electronica or more specifically “trip hop” and Mono’s music shares some similarities with other such acts including Sneaker Pimps and Portishead.

Dutch: Mono are a Dutch indie rock/post-rock band from Rotterdam. They are on Zabel Records, together with We vs. Death. http://www.monotheband.com

Austrian: Mono is a female Austrian reggae / dancehall artist who now mostly collaborates with the German artist Nikitaman forming the band Mono & Nikitaman. Both have recently moved from Düsseldorf, Germany to Linz, Austria.

Swedish: Mono is one of the names used by Jezper Söderlund, also known as Airbase, Ozone, PARC and RAH.

Korean: Mono (모노) was a Korean ballad trio active in the first half of the 90s. They released two albums in 1993 & 1994, and resurfaced for a new album in 2000.
