Consorzio Suonatori Indipendenti is an Italian band that evolved from the former punk/art band CCCP Fedeli alla linea.
C.S.I. were founded in 1992 by Giovanni Lindo Ferretti and Massimo Zamboni, along with original members of the Italian band Litfiba. The naming conventions of the band followed political changes occurring around the time of the fall of the Berlin Wall. Whereas the earlier band's name referenced the Cyrillic lettering for SSSR as it was wrongly pronounced by peasants in their Italian native region of Emilia Romagna, "CSI" follows the conventions of the Italian acronym for the newly established Commonwealth of Independent States.
After Zamboni departed in 2000, the remaining members of C.S.I. continued in the form of Per Grazia Ricevuta. C.S.I. split in 2001.
