Revelation is the debut album by the German psychedelic rock band Virus, who originated from the Bielefeld area in North Rhine-Westphalia. Thanks to numerous gigs in the region, they were one of the most popular local bands there. In 1970, they won first prize in a band competition held at the Vestlandhalle in Recklinghausen. The prize included recording sessions for an own LP at Star Studio Hamburg. With the support of the legendary Conny Plank as producer and sound engineer, the recordings took place from 5 to 7 January 1971. The result was released in March as the group’s first album on the newly founded BASF record label.

It contains long tracks with mostly psychedelic rock jams with heavy keyboards and hard-hitting guitars. Flute solos lend the sound a progressive edge, while influences from space rock are reminiscent of Pink Floyd. Unfortunately, the band did not find success with this music and disputes arose within the group, which at that time consisted of guitarist Werner Monka, organist Jörg-Dieter Krahe, singer and flautist Bernd „Molle“ Hohmann, bassist Reinhold Spiegelfeld and Wolfgang „Dicken“ Rieke on drums. Alongside extensive line-up changes, the musical style also changed on their second LP Thoughts, which was released just a few months later. Considered a minor masterpiece by many psychedelic rock collectors, their debut album now fetches high prices as an original German BASF pressing.
