I have quite a few compilations cassettes from the 80s, as you may have guessed and this thirty minute compilation is one. I believe it's loosely based around the theme of heartbeats, although its not always clear from the music. I think, but I'm not sure that the guy who ran this label was nurse. I have no clue who are on the other volumes, nor how many volumes there were. This one includes music from Onomatopeia, Alain Basso, professor Zeebuton Tourneboute, Jean-Pierre Bobittot, KWI, Kapotte Muziek, Merz, Ak Ak, M.I. Dotan and F.A.R.
