This week's show will be particularly enjoyed by fans of aggregate as we set about mixing up some concrete, from tunes with a cement or concrete theme to some examples of musique concrete by the likes of Pierre Henry, Tod Dockstader, Fred Judd and the BBC Radiophonic Workshop. We've also managed to shoehorn a little triptych of Quatermass-related tunes into the show, including a brand new track from Hong Kong in the 60s which comes from a cassette produced to accompany a monograph on the subject of one Nigel Kneale.
