Uh yeah, simply put Coroner was the shit. But then again, hey I thought a lot of bands that were good got the "short" treatment back in the day. For example: Seattle's Forced Entry, New Jersey's Whiplash (one of two good things to come from Jersey, the other being Overkill), S.F. Bay Area's Defiance, and even bands like the old Hirax ('85-'87) and one-hit-wonders U.K.'s Cancer (Death Shall Rise shreds...)
There were some great bands back in the day and even though history is written by the winners, Coroner still had a good deal -record companies would put their stuff out. As far as I'm aware, Grin (yes, a FINE ALBUM INDEED) is the only album of theirs out-of-print. That says something alone. Nuclear Assault was way bigger than Coroner ever was in the late eighties and all their stuff is unavailable to the casual listener. One of things that helped Coroner was they were associated with Frost (they were former roadies) so Coroner had committed sales proceeds from Frost fans. Coroner also wasn't that thrilling of a live act. Royce did a fine job, other than on "Grin" and "Mental Vortex" - the drumming is pretty pedestrian, but the real star is Tommi Vetterli. Insane and interesting riffs. Nothing like it.
