Mikael Åkerfeldt (last name pronounced Oh-ker-feldt) (born April 17, 1974, in Stockholm, Sweden) is currently lead vocalist and guitarist of Opeth. Mikael was the vocalist for Eruption, a death metal band which he formed in 1988. After Eruption came to an end in 1990, Mikael joined Opeth, ostensibly as a bassist. When vocalist David Isberg insisted Åkerfeldt join the band, all other members left. David assumed guitar duties, and when David left Opeth two years later, Mikael replaced him as a vocalist.
