Lindgren joined Opeth in 1991 as bassist for a show, but ended up switched to guitars. As explained in "The Making of Deliverance and Damnation" on Opeth's live DVD
Lamentations, lead-playing duties were based on ease of Mikael Åkerfeldt's vocal delivery and which of the two might want a given solo more. If Åkerfeldt was having trouble with a solo, he would hand it over to Lindgren, and vice versa. In March 2004, Peter and
Mikael Åkerfeldt were both ranked #42 out of the 100 Greatest Heavy Metal Guitarists of all time by
Guitar World. During his career in Opeth, Lindgren co-wrote the music for several songs along with
Mikael Åkerfeldt, such as "Black Rose Immortal" from
Morningrise, "Demon of the Fall" from
My Arms, Your Hearse, as well as "Dirge for November" and "Blackwater Park" from
Blackwater Park. In May 2007, Peter Lindgren announced that he had left Opeth due to the rigors of life on the road as a touring musician and because he had lost his enthusiasm for playing in Opeth. Both Lindgren and Åkerfeldt said that the split was amicable. Lindgren was since replaced by
Fredrik Åkesson. ==Personal life==
