Frank Zappa: Filthy Habits (original Sleep Dirt LP version) One of the most beautiful albums by F.Z. wrapped in a cover that is ugly and diametrically opposed to the content... an "almost" illegitimate child due to the dispute with W.B. It was supposed to be part of a quadruple box set, which indeed came out shortly after his passing, but W.B. did not publish it as he had conceived; instead, they divided it into 4 separate LPs devoid of instructional notes and references to the technical musicians, etc., infuriating the mustached one, who accused them of default (he was never paid for this lot of LPs) and of tampering with the recordings at their whim, mixing what he believed had a logical sense in a different sequence and claiming they had recorded them without the reference pitch, thus altering the tonality and coherence of the tracks!
