Toxic Frequency was the first electronic music project by multi-talented Mark Crumby (also in Binary, Cathedra, Konstruktivist, Sonic Perfection etc.) that never saw any releases whatsover as he already gave it up before there were any official products.
In 1999 Klanggalerie managed to fly Crumby in for a one-off Toxic Frequency live set in which he performed material that nobody had ever heard before except himself and a few lucky friends. This cassette is a document of a truly unique evening and will never be re-issued in any form.
