Children of Bodom's first world tour began in 2003 and lasted until late 2004. The tour had many sold-out concerts and marked the consolidation of the band in North America, but was also accompanied by an unexpected announcement: Kuoppala decided to quit Children of Bodom for personal reasons right in the middle of the tour without giving previous warning. In an interview, when Alexi Laiho was asked why Kuoppala left the band, he stated that, "Well, I try to be careful about what I say about him because there is no bad blood between us. He told me that he just got sick of touring and the whole band/rock 'n roll lifestyle living in hotels and tour buses and stuff. For me it was really weird because he was always the one who was SO into it! He was a die hard rock 'n roller and suddenly he made a quick 180 turn in his whole life. This whole situation involves a new girlfriend.". Laiho's bandmate from Sinergy, Roope Latvala assumed the guitars as a session player, until later joining the band as Kuoppala's replacement.
