Tau

Tau is a track from the 1981 album Sandhyā by Swiss percussionist Matthias Frey and Indian percussionist and composer Trilok Gurtu. The composition appears as the second track on the B-side (B2) of the original 12\" vinyl release.

The album Sandhyā was issued on November 1981 under the German independent label RillenWerke. The record explores fusion elements that blend Indian classical rhythms with contemporary jazz and avant-garde percussion. Frey contributed on Western percussion instruments, while Gurtu incorporated traditional Indian percussion, including tabla and mridangam.

Tau spans 5 minutes and 20 seconds and exemplifies the album’s cross-cultural experimentation. The track features layered polyrhythms, improvisational passages, and textural interplay between acoustic and electronic percussion. Specific compositional details, recording locations, or session musicians beyond the primary artists remain undocumented in available sources.

Sandhyā was released exclusively on 12\" vinyl with no confirmed reissues on digital or CD formats. The album cover and liner notes, where present, provide minimal contextual information about the recording process or artistic intent. The label RillenWerke operated as a niche imprint during the late 1970s and early 1980s, specializing in experimental and world music collaborations.

No commercial singles, music videos, or live performances of Tau have been verified. The track’s reception and critical analysis at the time of release are not widely archived, though later retrospectives on Gurtu’s early work occasionally reference the album as a precursor to his later fusion projects. Further details about the production, engineering, or mastering personnel are not publicly accessible.
