 In 1997 , after the tour , Åkerfeldt and Lindgren dismissed DeFarfalla for personal reasons , without the consent of Nordin . When Åkerfeldt informed Nordin , who was on a vacation in Brazil , Nordin left the band and remained in Brazil for personal reasons . Former Eternal members , drummer Martín López ( formerly of Amon Amarth ) and bassist Martín Méndez , responded to an ad at a music shop placed by Åkerfeldt . The Martíns were fans of the band and took the ads down themselves so no other musicians could apply for the job . Åkerfeldt and Lindgren did not want the Martíns to join at first , due to them already knowing each other ; they felt that they wanted two strangers so that there wouldn 't be two camps in the band , but eventually hired both . López made his debut with Opeth playing on a cover version of Iron Maiden 's " Remember Tomorrow " , which was included on the album A Call to Irons : A Tribute to Iron Maiden .
