Opeth
Opeth was scheduled to perform in Jordan in late 2003 without a crew due to the fear of terrorist attacks in the Middle East. Opeth's tour manager distributed 6,000 tickets for the concert, but before the band left for Jordan, Lopez called Åkerfeldt saying he was having an anxiety attack and could not perform, forcing the band to cancel the show. In early 2004, Lopez was sent home from Canada after more anxiety attacks on tour. Opeth decided not to cancel the rest of the tour, and Lopez's drum tech filled in for two concerts. Opeth asked drummer Gene Hoglan of Strapping Young Lad to fill in. Lopez eventually returned to Opeth for the Seattle show on the final leg of the Deliverance and Damnation tour. Per Wiberg also joined the band on keyboards, and after more than a year on tour, Opeth went back home to start writing more new songs in 2004.
