Following Disclaimer posted on KS Website, consider this before you go for this edition:In 2012, the German label "Made in Germany" released a double CD with two versions each of both Tonwelle tracks. They seem to believe that the original release with 45 RPM was wrong (!). At least their first promotion stated impressively and for some weeks: "on the original cover was wrongly given to play it in 45 RPM" & "the first editions on CD were in this 45 version, different as what the artist wanted" & "for the first time ever are now both versions available, the correct one and the involuntary wrong one." = ALL WRONG. Although I told them that the reason for their strange doing and the release itself is completely wrong, it doesn't hinder them to release this nonsense double CD anyway: one MiG version is circa 26% slower and the other version is circa 26% lower in pitch. The original version is not included (!) Besides, they sell this product now under "Klaus Schulze".
