Mogwai are a band from Glasgow formed in 1995. They compose lengthy, mostly instrumental guitar-based pieces in the style of post-rock, usually focused around the elaboration of a single theme, and are known traditionally for their quiet/loud dynamic, defined bass riffs, and an eminent ambient sound, sometimes dark and sometimes grand. Although frequently referred to as post-rock, the band have revealed in interviews that they despise this categorization, insisting that their sound bears little resemblance to pioneers of the genre, such as Tortoise. - From Last.fm Artist Summary
