Earthstar was an electronic music group originally from Utica, New York, in the United States. Earthstar was encouraged by Krautrock/Kosmische Musik/electronic music artist, composer, and producer Klaus Schulze to relocate to Germany where they were signed by Sky Records. Schulze produced their second and most successful album, French Skyline. Earthstar is notable as the only American band who participated in Germany's Kosmische Musik/electronic music scene while still at its height.
The Earthstar entry in the New Gibraltar Encyclopedia of Progressive Rock describes the wall of sound on the second and third albums: "[Group leader Craig] Wuest's vision propels these two albums, his desire apparently is to create music that doesn't necessarily suggest a particular instrument, rather creates a new texture. Therefore, though there are credits for flute, guitar, bass, violin, viola, French horn, sitar and vocals, it's pretty hard to distinguish any of these..." Earthstar's style on French Skyline has been compared to Wolfgang Bock, Sangiuliano, and Klaus Schulze's own recordings. Other albums have a softer style with more distinct instrumentation.
Earthstar is also notable for Craig Wuest's heavy use of the Mellotron and the rare Birotron, a variation on the Mellotron that can sustain notes beyond eight seconds.
