This tape is a Italian / British joint project from 1982 made possible by the international postal system of the time. MAP and Vittore had got in touch through the global cassette culture networks then operating. Vittore had sent MAP many tapes from his TRUX cassette label and MAP had retaliated with firstly his MAP TAPES back catalogue, then with MAP7s. MAP recently told me that this is the explanation for the large number of MAP7s produced; a simple need to keep up a response to Vittore's prodigious mailings. Eventually MAP sent Vittore a cassette tape of backing tracks, especially composed for the Italian to use, and the result, in this case, was … THE COP KILLERS.

Here is a review from Cassette Gazette (I think), a UK-based Cassette-zine of the time: "Fourth 'Trax' cassette, this one differs from the first three, mainly because it isn't a compilation…but an 'audio-tract', a kind of cassettophonic tale which has been realised by Vittore Baroni (Script, Voices, Production) with the sounds of M.A.P. (Synth, Casio, Rhythms, Noises) and Daniele Cuillini (Synth, Noises). MAP is a well known figure for the readers of CG (see 'The Dadacomputer', CG 6), the sound texture of this cassette is equal to that masterpiece. The result , under the title 'Report of a torture performance in the Cop Killers Caberet Lounge', is to say the least convincing, horror and humour, rhythm and chaos, in a controlled/dadacomputerised atmosphere where Cop Killers abound nevertheless. It is said in the 'tract' that 'the ULTRAX Theme reached the top of the Eurasian Charts on the 19th of June 2056'. All the same, don't wait to be a hundred years old, before listening to it."
