I'm going to totally hijack this thread because Air initially put their earliest music out on Stereolab's Duophonic Super 45's. Apparat Organ Quartet, Broadcast, Pram, Tortoise and Labradford remain my favourite bands on that label. Avoid Imitation Electric Piano because they are too coffee table (together with the majority of Air's Moon Safari).
