The group released several albums through 1993, ending with a greatest hits collection, Coroner, in 1995. Lack of media exposure brought this band to disbanding in 1994 — and eventually to their farewell tour consequent to their self-titled album.
In March 2005, talks of a reunion were in the works, but later retracted. The main reason was that neither Marky, Ron, nor Tommy had the time it would require to do this properly, and also that neither of them liked to, quote, "reheat things, except spaghetti sauce."
The second album, Punishment for Decadence, saw a progression into a more complex sound with a unison of bass and guitar. Tempo changes interspersed mid-paced sections and the odd slow passage between the faster passages started to emerge. Lyrically, Coroner began to write about themes such as politics and personal introspection.
The production of No More Color by Pete Hinton and the band, was an improvement. Moreover, Coroner's music became more technical on No More Color as the guitar work was characterized by intricate modes and arpeggios, solo work that was chromatically colorful, as well as the de rigueur crunchy chords and speed runs; the drumming went beyond the 4/4 time of Coroner's two previous albums to incorporate odd time signatures which became their trademark. The bass player is also worth a mention as having an advanced three-finger technique which enables him to double the rhythm line as well as perform intricate riffs. Prime examples of this are the opener "Die By My Hand" with its vicious riffing and the harmonic minor inspired riff in the middle of "Mistress of Deception". There is a dark mood on this album that could be classified as death metal yet spans many influences from other metal genres. The closer "Last Entertainment" is a prescient take on TV.
Mental Vortex improved over No More Color. Continuing with the previous album's technical formula, the speed metal formula was re-integrated into Coroner's sound on this album but with a tone that made it sound not at all like R.I.P. or Punishment for Decadence. There were slower songs but none of the songs on Mental Vortex stayed the same speed for very long. The songs on Mental Vortex ranged from four to eight minutes. Overall, the tone was a shift from the thrash-tech of No More Color which showed them gravitating towards their opus Grin.
Grin saw a much more industrial sound and was a natural progression from Mental Vortex but was different from most of their previous material. It involved a much more reflective guitar riff and underlying bass line. It was slower and more refined in its metal sensibility. Brooding guitar over Royce's bass produced an almost hypnotic trance-like sound on some tracks.
