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.
