Dunno, but definitely not Radio-activity. There are a few tracks on it that don't do a lot for me.
I sold my vinyl copy of Radioactivity 22 years ago when foolishly filleting my record collection - It seemed at the time neither fish nor fowl - they hadn't quite hit the formula that they refined on Trans Europe Express, but lacked the free form experimentation of the early albums. Of course, Autobahn was also a transitionary album, but was more interestin imho. I've now got an annoying gap in my Kraftwerk collection which I probably won't fill as Radioactivity on vinyl seems to go for silly amounts of money nowadays. Heard some of it again on the Freak Zone a while back and it sounded really good.
