Opeth has announced that touring keyboardist Per Wiberg (Spiritual Beggars) has been made an official full-time member of the band. In other news, the group will be inviting journalists for a special in-studio listening/interview session later this month. After that, they'll be back on the road as part of the 'Sounds of the Underground' tour in North America which kicks off on June 25 in Lowell, Massachusetts. Scandinavia and European tourdates will soon be confirmed for September, around the same time the new album is due out.
