Originally part of the road crew for fellow countrymen Celtic Frost, Swiss thrash trio Coroner—made up of bassist Ron Royce, drummer Marquis Marky and guitarist Tommy T. Baron—went on to become one of the most progressive extreme metal acts of the Eighties.

The connection between the Zurich band and Celtic Frost was so strong, in fact, that Frost frontman Tom G. Warrior offered to handle vocals for the emerging band’s demo. Warrior and Coroner entered Switzerland’s Magnetix studio on October 10, 1985, and nine days later they walked out with the impressive four-song 1986 release, Death Cult.

While subsequent bootlegged CDs included the bonus tracks of “Arrogance in Uniform” and “Hate, Fire, Blood,” the original four-track demo consisted of the following tracks: “Spectators of Sin,” “Spiral Dream,” “Aerial Combat” and “The Invincible.” (Only “Spiral Dream” would make it onto Coroner’s 1987 debut LP, R.I.P.)

After getting some serious scene recognition for Death Cult, the group went back into the studio to record its first full-length, R.I.P., on which Broder took over vocals.

Check out this classic gem of progressive thrash, and dig the technical prowess that these guys possessed even at such an early stage in their careers.

In 1985, San Francisco’s Possessed released their now-legendary death metal debut Seven Churches.

Not only did Seven Churches‘ blend of thrash riffs, grunting vocals and blistering leads send shockwaves of excitement throughout the underground tape-trading scene of the day, but the album’s final track, “Death Metal”—and Possessed’s 1984 demo of the same name—just may have given an official name to the genre that had already spawned such American bands as Death, Morbid Angel and Master.

Months before Seven Churches hit the stores, cassettes of Death Metal had been spreading throughout the extreme metal community. While the tape typically traded contained four tracks: 1) “Death Metal,” 2) “Evil Warriors,” 3) “Burning in Hell” and 4) “Fallen Angel,” the original self-produced demo did not contain “Fallen Angel.” “Fallen Angel” was reportedly recorded during the Death Metal session, but did not make the official demo, because it was banged out quickly at the end of the recording session. But, through the tape-trading process, “Fallen Angel” became tacked on to the end of Death Metal.

Torrao, Becerra, Lalonde and Sus

While the classic Possessed lineup is universally considered to be bassist/vocalist Jeff Becerra, guitarist Larry Lalonde (who went on to gain notoriety as a member of Primus), guitarist Mike Torrao and drummer Mike Sus, the lineup for the Death Metal demo was Beccera, Torrao, Sus and guitarist Brian Montana.

After Seven Churches, Possessed released another full-length studio album, 1986’s Beyond the Gates, and an EP the following year called The Eyes of Horror (produced by Joe Satriani, oddly enough). The group disbanded soon after, and in 1989 singer Jeff Becerra was shot while being robbed on his way home and left paralyzed from the waist down. Although confined to a wheelchair, Becerra is still planning to appear onstage with a reunited Possessed at the Wacken Open Air festival in Wacken, Germany, on August 2-4.
