Sand emerged in the early 1970s as a fleeting one-album curiosity whose sole release might have vanished into complete neglect until David Tibet from Current 93 happened upon their album Golem inside the record holdings of Steven Stapleton from Nurse with Wound. Their output of eerie, dreamlike sound stands as an utterly distinctive pinnacle within the realm of cosmic Krautrock. Hailing originally from the modest settlement of Bodenwerder in Lower Saxony, located in northwestern Germany, the musicians took shape in 1970 when Johannes Vester joined forces with brothers Ludwig Papenberg and Ulrich Papenberg along with additional players to establish Part of Time, drawing inspiration from Pink Floyd, Jimi Hendrix, and further psychedelic acts of the era. Following numerous live appearances, the collective relocated after a brief period to Cologne, where encounters occurred with Can members as well as Klaus Schulze. By 1971 Vester had shifted to Berlin for psychology studies, prompting the Papenberg brothers to accompany him, at which point the three-piece adopted the name Sand in 1972.
Their sound had by then absorbed stronger currents from the city's experimental rock community along with the insurgent political currents running through Berlin's counterculture. Klaus Schulze was then refining, alongside engineer Manfred Schunke, a distinctive recording method known as Artificial Head Stereo Sound that generated an enveloping spatial illusion comparable to Surround Sound. Having already crossed paths with the musicians during their Cologne phase, Schulze selected them to document one installment in a sequence of releases intended to showcase the technique. The resulting album Golem was captured in 1974 under Schulze's engineering supervision and issued the same year on the Delta-Acoustic imprint as part of that year's Artificial Head series. The musicians themselves felt dissatisfied with the compression of dynamic range introduced by the Artificial Head process, even while it imparted an intensified hallucinatory quality best experienced through headphones.
The ensemble disbanded soon after the album appeared, whereupon Vester launched a solo endeavor in 1975 under the cumbersome title Johannes Vester & His Vester Bester Tester Electric Folk Orchestra. That project returned to the Artificial Head Stereo Sound facility to lay down the unreleased album Born at Dawn, while the Papenberg brothers returned to Lower Saxony to pursue separate professions. Stapleton and Tibet later reached out to Vester, resulting in the 1996 double-CD Ultrasonic Seraphim that gathered the complete Golem alongside additional Sand material and alternate versions plus three tracks drawn from Born at Dawn.
