德国前卫摇滚乐团Guru Guru成立于1968年，最初成员有Mani Neumeier (drums, percussion, vocals), Ax Genrich (guitar, vocals, 1968-74), Uli Trepte (bass, 1968-73)。
UFO是Guru Guru的第一张专辑，即兴爵士风格的渗入让UFO于同时期其他前摇专辑显得与众不同，从而确立了乐团在Kraut Rock乐史上的独特地位。
Guru Guru's classic debut album has to be one of the definitive moments in the Krautrock chronology. It is a monster work, and one which severely assaults the consciousness with waves of desert scorched guitar lashes along with acid laced, enchantingly amorphous rhythmic pulsing. On first listen the album appears sloppy, disjointed, confused and almost incomprehensible. Further listens will reveal a well of focused, completely intentional creative drive that makes UFO one of Krautrock's most immense sonic statements. Open minded listeners, and fans of the kind of cosmic jamming that typify many of the other guitar oriented Krautrock bands, will no doubt adore the album. While lacking the up-tempo, driving fury of say, Ash Ra Tempel's debut, UFO finds Guru Guru creating hulking, downbeat walls of guitar drenched intensity. Like Black Sabbath on an orgasmic acid trip, the rhythm section shows little regard for set "beats", time signatures and the like, preferring to create bruising heaps of bass grooves and cymbal crashes, speeding up, slowing down and falling completely off the tracks as they see fit. Above this, guitarist Axel Genrich contributes layers of blistering guitar, guiding the band from climax to shivering cataclysm.
Once the initial shock wears off, UFO is actually a thoroughly enjoyable album, though among the more adventurous works in an already pretty "out there" musical climate. Indeed, I might even prefer subsequent albums like Hinten and, in particular, KanGuru on a purely aesthetic level, given their greater compositional cohesiveness and ability to retain a groove. Parts of the title track are a little too empty and cacophonous even for me. That said, UFO remains the band's biggest statement. Hell, how can one help but view an album with a title like "Der LSD Marsch" with fondness?
