'We continue our fascination of the late, great British broadcaster John Peel with another excellent show from the archives. This time the collaboration of two sonic visionaries in 1973 that produced the often talked about album No Pussyfooting that was designed to showcase tape-echo and delay techniques to the mass pop audience. Here, the gentlemen offered two tracks exclusively for Peel's Top Gear show.'
