Yochk'o SEFFER always created varied and interesting works during his long career, be it with MAGMA, ZAO, NEFFESH MUSIC, his teammate François "FATON" CAHEN or all alone. In each of his records, the French saxophone-player tries to pay tribute to his Hungarian roots, with jazz-rock music close to ZAO, but with free tendencies. "Chromophonie" compiles two volumes, originally released in 1981 and 1982, with the notable support of Hungarian violinist Lajos HORVATH and the QUATUOR MARGAND. "Magyar Etno" unites popular music from Hungary with free and dissonant jazz. "Yog I - Pitchipoy" (1997) keeps on carrying NEFFESH MUSIC's spirit, as flaming as ever. The development of complex and structured themes are linked with frenetic saxophone parts, blended with other instruments. It can be described as the crossing point between works like "Ghigoul" or "Chromophonie". "Yog II - Sefira" (1998) follows the same path with an equal talent: Thierry MAILLARD, Dominique BERTRAM and Sylvain MILLER are here as well. "My Old Roots" is a collection of pieces recorded between 1976 and 1980.
