Before Opeth Starting early with a band he called Satanic Slaughter, which he renamed as soon as he heard about another band from Sweden with the same name and demos out to Casket. Casket played two live shows. David appeared in the grindcore band Dr. Deaths Armageddon playing a few shows and releasing 1 live cassette and one rehearsal demo. David was in the Swedish death/black metal band Procreation (1989–1991). In Procreation, he used the alias of The Unholy Emperor. Alongside David was Christofer Johnsson, the man most known for being the frontman of the band Therion, using the name Necro. Procreation made two demo tapes ("Enter the Land of the Dark Forgotten Souls of Eternity" 1991 and "Procreation of the Antichrist" 1990, along with two live shows (both at Hunddagis, Handen 1 held in 1989 or 1990 (the year is not confirmed) and the second show being held on 23 February 1991 (to celebrate David's 16th birthday) with various Therion members filling in on the empty slots. Opeth David formed Opeth with some friends from Täby in the Spring of 1990. Long-time friend Mikael Åkerfeldt was in a band called Eruption, but was considering a departure from this group. David invited him to play bass for Opeth and Åkerfeldt accepted the offer. When he came to the rehearsal, however, none of the other members of the band knew Mikael was coming and they did not want to kick out the bass player they already had. The ensuing argument played out with all the members of Opeth (aside from David) leaving. They renamed themselves Crowley and released a demo tape called "The Gate" in 1991. David remained with Opeth until 1992 when he left citing creative differences. His duties as a lead singer were taken up by Åkerfeldt.
