Eruption started in late 2004, when Klemen Kalin (vocals) and Tim Tajič (guitars) got together with a bunch of guys with a shared passion for thrash metal. They started jamming together at a shitty rehearsal space, covering classics by Exodus, Forbidden, Metallica and Testament, all the while writing their own material. When Borut Rampih (drums), Matic Jeraj (guitars) and Juš Premrov (bass guitars) joined the band, the first steady line-up was formed. All this was happening just before the new wave of thrash became a big thing, so they didn't really know what to expact from the public. Lucky for them, the response was great!
