 On May 17 , 2007 , Peter Lindgren announced he would be leaving Opeth after 16 years . " The decision has been the toughest I 've ever made but it is the right one to make at this point in my life , " Lindgren said . " I feel that I simply have lost some of the enthusiasm and inspiration needed to participate in a band that has grown from a few guys playing the music we love to a worldwide industry . " Ex @-@ Arch Enemy guitarist Fredrik Åkesson replaced Lindgren , as Åkerfeldt explained " Fredrik was the only name that popped up thinking about a replacement for Peter . In my opinion he 's one of the top three guitar players out of Sweden . We all get along great as we 've known each other for maybe four years and he already has the experience to take on the circus @-@ like lifestyle we lead as members of Opeth . "
