Second and last album of the band Virus, released only six month after their debut Revelation in 1971. During this time, three band members left due to internal disputes to form the German-British band project Weed with Ken Hensley and two other musicians. But not only the group changed radically, but also their music. The songs were now much shorter and more song-orientated. The psychedelic Krautrock jams with progressive leanings were exchanged for a conventional and straightforward, bluesy hard rock with English vocals. Only Conny Plank could be engaged again 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 sub-label Pilz.
Unfortunately, this album also failed to attract any attention as, despite the high level of musical ability, it lacked the originality to really stand out from the mass of countless bands in Europe and America playing classic hard rock from the early 70s. As with the debut album, high prices are paid for Thoughts in collector circles today.
