Mats, according to an interview, also mentioned how well-developed the German recording scene/studio musician scene was back in the 70s and 80s. I mean, just from the libraries alone, SONOTON, COLOURSOUND, INTERSOUND and the likes pioneered (with SONOTON bringing the concept of underscores into play if I remember correctly). He also never actually met Donna Summer though and for Boney M. it took him 2 years to actually meet them in person. Whilst those names are featured on the sleeves of hot sellers and associated a lot with known library musicians, most of the stuff seems to be pretty "grounded" studio work. The aforementioned "Farian-esque" sound of the HAPPY RECORDS albums he contributed (I just re-listened "MOSAIQUE 2") are just another sign that they "just made music" for whoever requested them and if not, they'd produce something on their own - library music. That is what I gather from that. I often pondered what these people do. Living only off of the licenses - I always doubted that's enough.
