Although Helsinki, Finland heavy metal band Stratovarius was formed in 1982 by drummer Tuomo Lassila, the group did not record its debut album, Fright Night, until 1989 (after which Lassila departed). 1992's Twilight Time established a fan base in Japan, becoming the biggest-selling import of that year; Stratovarius consolidated its Japanese popularity with an extensive tour of the country behind 1994's Dreamspace. Following 1995's Fourth Dimension, the lineup shifted to include vocalist Timo Kotipelto, guitarist Timo Tolkki, bassist Jari Kainulainen, ex-Yngwie Malmsteen keyboardist Jens Johanssen, and drummer Jorg Michael. This lineup added a choir and orchestra for 1996's Episode in 1996 and 1997's Visions, the latter of which was released in the U.S. early in 1998. American reissues of most of Stratovarius' previous output followed over the course of the year, and in the spring of 2000 the group issued Infinite. Intermission appeared the following summer. ~ Steve Huey, All Music Guide
