Hailed in the early seventies as the best Italian group of avant-garde jazz/rock along with Area and Perigeo, in the mid-seventies, with the release of their second album, Dedalus started a much more uncompromisingly experimental approach to music through the use and combination of disparate musical materials: improvisation, electronic music and musique concrète techniques, elements of contemporary classical composition, folk tunes, jazz, use of self-built and modified instruments for timbric research, etc., with much conviction and totally unique and beautiful results. This disc re-issues their very hard-to-find second album, Materiali per tre esecutori e mastro magnetico with the addition of about 40 minutes of material recorded in the year following the release of the album, most of which was produced specifically for a record to be released on Cramps Records' historical DIVerso series, which remained unpublished because of the label's discontinuance. Most of the material was recorded by the trio composed of Fiorenzo Michele Bonansone (cello, piano, Fender piano, voice, accordion, synthesizer, soprano ocarina, electrified mandolin, pipe, bottlephone), Marco di Castri (tenor and soprano saxophones, electric, acoustic, prepared or bent guitars, harmonica, flute, Moroccan oboe, pipe with reed) and Enrico Grosso (drums, percussion and noises) -- with the help of Ennio Bonansone as sound engineer on the pieces from the album -- and part as a duet by Fiorenzo Michele Bonansone and Marco Di Castri
