The late 1960's psychedelic rock scene also spawned the birth of the space rock genre. The pioneering acts of this genre assimilated krautrock elements like repetitive hypnotic beats and electronic/ambient soundscapes as they moved away from the common musical and compositional approach. The synthesizer with its bubbling tones and spacey patterns, provoking a gliding flow, is a typical instrument of this genre. Guitars are by preference played with glissando technique and delay/echo effects are heavily used, and elements originating from reggae/dub are fairly common. Several bands combine their live performances with trippy lightshows using random fractals. Albums in this genre will often include at least one long meandering jam based on a main theme, where loops and wavelike fluctuations provides slight variations to this structural foundation.
Stories, images, song titles and album names referring to cosmic themes are fairly common features of the genre. HAWKWIND's live album "Space Ritual" is said to be the ultimate space rock album due to the collaboration with sci-fi author Michael Moorcock. His lyrics are performed by a narrator and underlaid with synth elements. PINK FLOYD can be regarded as pioneers of spacey music during the band's early phase, as exemplified by certain tracks from "The Piper At The Gates Of Dawn" or the stirring live performance of "Careful With That Axe Eugene" from "Ummagumma". GROBSCHNITT provides another fine example of classic space rock with their epic effort "Solar Music". Other bands explored the space rock sound for a limited time period only. GONG released groundbreaking albums in the genre at the start of their career, while British hard rock band UFO released the extraordinary album "Flying - One Hour Space Rock" as their sole contribution to the genre in 1971.
A space rock scene can be found in most countries sporting artists producing music with a western-oriented or influenced sound. Swedish bands are known for a brisk exchange of musicians among each other. The "Strange Daze" festivals from 1997-2000 showcased the American space rock scene. Japan is an inexhaustible reservoir of artists exploring both psychedelic progressivce rock and progressive space rock. Representative examples of the style are bands such as ORESUND SPACE COLLECTIVE with their focus on long grooving improvisations, QUARKSPACE and OZRIC TENTACLES with their stronger emphasis on electronic elements and VESPERO and HIDRIA SPACEFOLK with their inclusion of ethnic-originating musical components. Other groups like ESCAPADE and THE LEGENDARY PINK DOTS represent an avantgarde approach to the genre, whereas the SUBARACHNOID SPACE and KINSKI are examples of artists that provide transitions to the post rock genre
Ozric Tentacles is pretty good.
Nektar (another fav.)
