Isis was a Los Angeles, California-based post-metal band, founded in Boston, Massachusetts, with a career spanning from 1997 to 2010. They borrowed from and helped to evolve a sound pioneered by the likes of Neurosis and Godflesh, creating heavy music consisting of lengthy songs that focus on repetition and evolution of structure.
The band's last album, Wavering Radiant, was released on 5 May 2009. They disbanded in June 2010, just before the release of a split EP with the Melvins.
