Due to "previously scheduled commitments," bassist Sean Tibbetts will be unable to join American/Norwegian metallers KAMELOT for their upcoming appearances at this year's Rock am Ring and Rock im Park festivals, set to take place June 4-6, 2010 in the German towns of Nürburgring and Nürnberg, respectively. Temporarily replacing him for these gigs will be KAMELOT's longtime producer Sascha Paeth.Greek guitarist Gus G. (OZZY OSBOURNE, FIREWIND, DREAM EVIL, ARCH ENEMY), EPICA singer Simone Simons and Jon Oliva (mastermind of SAVATAGE and JON OLIVA'S PAIN, co-creator/songwriter of the TRANS-SIBERIAN ORCHESTRA) are among the artists who are scheduled to make guest appearances on KAMELOT's forthcoming album, tentatively due this fall. Songtitles set to appear on the CD include "House On A Hill", "The Great Pandemonium" and "Hunters Season", the latter two of which were performed on the band's recently completed European headlining tour. Simone — the longtime girlfriend of KAMELOT keyboardist Oliver Palotai — previously appeared on the song "The Haunting", which was included on KAMELOT's 2005 album "The Black Halo". KAMELOT spent time at various studios — including the Gate Studio in Wolfsburg, Germany — under the watchful eye of Sascha Paeth and Miro as producers working on the highly anticipated follow-up to "Ghost Opera". "The new songs are really inspiring," stated guitarist Thomas Youngblood. "We feel the long touring and time away from writing has been perfect for new ideas and an aggressive approach to the new songs." KAMELOT will embark on its first North American tour in two years this fall. Support on the trek will come from LEAVES' EYES and BLACKGUARD.
