Thoughts was the second and final album by the band Virus, released just six months after their debut Revelation in 1971. During this period, three band members left due to internal disputes to form the German-British band project Weed with Ken Hensley and two other musicians: guitarist Werner Monka, singer and flautist Bernd Hohmann, and bassist Reinhold Spiegelfeld. But it was not only the line-up, now with four new members, that changed radically, their music did too. The tracks were now significantly shorter and more song-oriented. The psychedelic rock jams with progressive influences were exchanged for a conventional and straightforward bluesy hard rock style featuring female English vocals.

During the recording sessions from 12 to 14 July 1971 at Star Studio Hamburg, Conny Plank was the sound engineer this time, and Jürgen Schmeisser could be engaged as producer. To add to the confusion, it was not BASF who took over the LP production and marketing, as was the case with the debut album, but their newly sub-label Pilz. Unfortunately, this album with cover art by J.H. Löffler also failed to attract any attention as, despite the band’s high level of musical ability, it lacked the originality needed to truly stand out from the mass of countless bands in Europe and America playing classic hard rock from the early 70s. Like the debut album, the follow-up album Thoughts, released on the legendary Pilz label, is now very rare and therefore in extremely high demand amongst collectors.
