Free Orbit
Free Jazz Goes Underground
Hamburg, 1969. A drummer recently arrived from Westphalia, known around the Jazzhouse on Brandstwiete as a capable timekeeper who could swing in 4/4 and play rock beats, which is why Klaus Doldinger had hired him for Passport. His name was Udo Lindenberg. Free Jazz Goes Underground, released by MPS in 1970 under the name Free Orbit, is the first studio album of the band he led, and he sings on it, in English, alongside a second vocalist.
MPS's own note on the reissue admits you need careful list…
