With a load of records I didn't know. At first I thought they must all be Krautrock since the only things I recognised where Kraftwerk's 3rd album and a Can album (Delay).
Later I realised there was also a Spaceman 3 LP and a Serge Gainsbourg best of called 'Initials SG'.
However, with no headphones and no idea what the things would sound like the majority of my time between the bands was spent picking records based on how good their covers were.
Then I tried to make Friends of the Bride at the Barfly but I was too late thanks to a schedule change. :'(
