Fröhliche Eiszeit existed from late 1979 to 1983, and released their recordings on cassette, of which only a tiny quantity seem to exist, they also contributed to at least one rare compilation during that period.
This is a compilation of tracks recorded in various locations, as per the LP title. The quality of the recordings varies from good to rough, some seem to be dubbed off vinyl and other n-generation sources.
The credits appear to be of a not very helpful list, ie 'these people played instruments... these people sang... these people wrote the lyrics...".
I guess we are lucky to finally have these recordings on vinyl, even though only 300 copies were pressed.
Note that there is an earlier compilation LP of different songs, though again only 300 copies were pressed.
