The album Grand Illusion, out in 2005, featured many special guests, including Jens Johansson (Stratovarius), Henrik Danhage (Evergrey), Kristoffer W. Olivius (Naglfar), Stefan Elmgren (HammerFall), and, more surprisingly, the Swedish world champion of cross-country skiing (three times world cup gold winner), Per Elofsson who comes from the same town as the band, Umeå.
In 2005 he made an unexpected appearance on the album Grand Illusion by the Heavy metal band Nocturnal Rites, playing guitar on one song.
