Mental Vortex is the fourth album by the Swiss thrash metal band Coroner, released on 12 August 1991.

## Musical style

Mental Vortex sees Coroner continuing the experimental formula from its predecessor No More Color (1989), showcasing a mixture of thrash metal with progressive, jazz fusion and avant-garde influences, while "unbridled speed and aggression were replaced by highly technical and unconventional songwriting".

## Reissues

After being out of print for many years, Noise/BMG reissued the album in 2018, remastered with the same track list in a digipack cd case, with additional photographs of the band and memorabilia.

## Track listing

All lyrics are written by Marquis Marky, except where noted.
