Q:A friend asked me to answer this question: What was the name of the person that played bass guitar on  My Arms, Your Hearse?, using the article: Opeth recorded its debut album, Orchid, with producer Dan Swanö in April 1994. Because of distribution problems with the newly formed Candlelight Records, the album was not released until May 15, 1995, and only in Europe. Orchid tested the boundaries of traditional death metal, featuring acoustic guitars, piano, and clean vocals.After a few live shows in the United Kingdom, Opeth returned to the studio in March 1996 to begin work on a second album, again produced by Dan Swanö. The album was named Morningrise, and was released in Europe on June 24, 1996. With only five songs, but lasting 66 minutes, it features Opeth's longest song, the twenty-minute "Black Rose Immortal". Opeth toured the UK in support of Morningrise, followed by a 26-date Scandinavian tour with Cradle of Filth. While on tour, Opeth attracted the attention of Century Media Records, who signed the band and released the first two albums in the United States in 1997.In 1997, after the tour, Åkerfeldt and Lindgren dismissed De Farfalla 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. López and Méndez 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.With a larger recording budget from Century Media, Opeth began work on its third album, with noted Swedish producer Fredrik Nordström, at Studio Fredman in August 1997. Although..., what would be the answer ?
