Tribes of Neurot is an American experimental music group formed by the members of Neurosis in 1995.
For example, their album Adaptation and Survival (2002) consists entirely of insect noises which were mixed and altered similar to Musique concrète, to create something that sounds entirely different from the source material.
Their albums can be wildly diverse, but Tribes of Neurot is often influenced by atmospheric dark ambient and similar genres.
Tribes of Neurot's Grace epitomizes this: released alongside Neurosis' Times of Grace, the two discs are meant to be played simultaneously for an enhanced experience that neither disc delivers on its own.
The future of Tribes of Neurot is uncertain, given the 2022 announcement that Neurosis frontman Scott Kelly had been quietly expelled in 2019 from the band due to abusing his wife and family, news of which was not announced at the time due to a request for privacy from Kelly's wife.
