For the longest time, I had it in my head that Fischer Z was German, but they were actually a British New Wave band—sorry guys—who lasted from 1979 through to about 2002. The head of the band was a guy named John Watts, a former student of clinical psychology and someone who worked a lot with the mentally ill.
If you know that, then a lot of Fischer Z’s songs take on extra meaning. Take this track, for example, from their 1980 album, Going Deaf for a Living. If you can track down a copy of the record, do it. It’s still a cult hit throughout Europe.
