Hi,
Apparently done on the same day ...
Apocaliptyc Bore - Amon Duul 2 (Vive la Trance // 6th album by AD2)
Fly to the Rainbow - Scorpions (Fly to the Rainbow // 2nd album by Scorpions)
One song is goodbye to drugs, and the other is hello ... let's have fun and party ... and I think that both songs were a dig about each other, and I think that AD2 did this after Scorpions, and said ... look my violin can be as good as your guitar in a duet! I still think that the songs are about each other, and not anything else, with AD2's lyrics suggesting no one cares about anything anymore at the end ... and that was where the "meaningful" album stopped. After that it was just a bunch of songs, and while nice, not half as good as the real AD2.
