The album "Tonwelle" is the result of Klaus Schulze's collaboration with some well-known musicians. Therefore, the album was released in 1981 as a vinyl under the artist name Richard Wahnfried, feat. Among others, Manuel Göttsching (Ash Ra Tempel) and Michael Shrieve (Santana).
This original vinyl release was intended to be played at 45 RPM, but Klaus has already mixed the album so that it can also be played at 33 RPM.
The now released version is newly mastered to be played at 45 RPM from an original mint vinyl that had never been played.
