Anders Nordin and his long-time friend Mikael Åkerfeldt started jamming together in Mikael's cellar in Sörskogen, Sweden when they were about nine years old.
In the end of 1987 they came up with the name Eruption for what was going to be their band. In the beginning they played mostly death metal covers like Bathory, Death and other bands.
Despite some line-up changes Eruption stayed alive between 1987 and 1990. They never did any gigs or demos, only some rehearsal tapes.
In 1990 the band had a stable line-up and the band went on under the name Opeth.
In 1997 Anders Nordin had gone to Brazil on vacation but when he called back home he told his friend and band-mate Mikael that he was going to quit the band and move to Brazil.
Since Anders had left, it was Martin Lopez, former Amon Amarth-drummer, who replaced Nording behind the skins.
