There are at least seven artists that have used the name Isis: 1. Isis is a Los Angeles, CA based band that started in Boston, MA in 1997. They borrowed from and helped to evolve a sound pioneered by the likes of Neurosis and Godflesh, creating heavy music consisting primarily of lengthy songs that focus on repetition and evolution of structure and texture. As such, their music encompasses a considerable range of genres. Some of these include sludge metal and post-metal; the band is considered a pioneer of the latter sub-genre.
