For today's adventures, I'm listening to the Kosmischer Läufer records (which claim to be part of a secret music-based East German Olympic training programme... I'll let you decide whether to believe that or not). Here's a sample:
There are five EPs and albums in total (all on Spotify, if that's your thing), and are exactly what is needed for a space adventure rooted in an early 80s dream. I wholly recommend them.
[EDIT: no there aren't, there are four, plus one live recording.]
