"The earliest tape used in this radio show comes from 1982 and the most recent is ten years old. AER is/was a name I gave to sound recordings used for the Touch samplers (in particular) and this is no more than an opportunity to clear the cupboards and make the best of them available in one location. None of them benefit from studio production and in the age of easily-available sound recording software, I suppose part of the point is that they are all cassette or minidisk recordings assembled on pre-digital recording equipment."
