Chaosphere is the third studio album by Swedish extreme metal band Meshuggah. It was released on 9 November 1998 by Nuclear Blast, and is the only studio album to feature bassist Gustaf Hielm. Chaosphere's sound shows the band toning down some of the thrash style of their previous releases in favor of the technical, polyrhythmic, groove-oriented sound they would continue to explore on subsequent albums. A video was made for "New Millennium Cyanide Christ". Jens Kidman – vocals Fredrik Thordendal – lead guitar, keyboards Mårten Hagström – rhythm guitar Gustaf Hielm – bass Tomas Haake – drums, vocals (tracks 6–7, 12) User-contributed text is available under the Creative Commons By-SA License; additional terms may apply.
