Swedish metallers OPETH were recently forced to cancel their appearances at the Peace & Love (Borlänge, Sweden on June 26), Hovefestivalen (Norway on June 27), Metaltown (Gothenborg, Sweden on June 28), and Graspop Metal Meeting (Dessel, Belgium on June 29) festivals after the group's guitarist/vocalist Mikael Åkerfeldt contracted varicella (chicken pox). Mikael has since issued the following update on the band's upcoming touring activities:"Just to avoid any confusion, I want to confirm that I'm feeling much better and OPETH will be performing the remaining summer festivals that we've committed to, starting with Ruisrock [in Turku, Finland] this Saturday [July 5]." "Watershed", the new album from OPETH, sold more than 19,000 copies of in the United States in its first week of release. "Watershed" is the follow-up to the band's acclaimed "Ghost Reveries" CD, which debuted at No. 64 on the Billboard chart back in September 2005 with first-week sales of just under 15,000. OPETH's 2003 album, "Damnation", opened with a little over 5,000 copies. "Ghost Reveries" has sold more than 95,000 copes in the United States since its 2005 release, according to Nielsen SoundScan.
