Gigantic Brain

American experimental music duo composed of John Brown, who started the project by himself, and Mastin Simmons, which was formed in the early 2000s in Virginia, United States. Gigantic Brain is known to be one of the original pioneers of the cybergrind subgenre of grindcore. The project's genre-defying style has changed dramatically throughout the years. Originally exhibiting a grindcore style, the group has more recently ventured into post-metal, ambient, industrial metal and sometimes post-rock.
