Shaped by Cláudio Cruz (first violin), Igor Sarudiansky (second violin), Horácio Schaeffer (viola), and Alceu Reis (cello), the Quarteto Amazônia is among the most significant Brazilian chamber teams. It includes a repertory of compositions by Mozart, Beethoven, Brahms, Ravel, and Schubert, however the group is certainly constituted, in its bulk, by functions of Brazilian composers, from essential though obscure functions just like the two “Quartetos” by Lorenzo Fernandez. The quartet’s documenting of Heitor Villa-Lobos’ “Quartetos Nos. 7, 8, 9, 10, and 11” was awarded in 1997 as the very best Recording by APCA (Association of Artwork Critics of São Paulo). Having also documented with achievement another recording that difficulties the frontiers between traditional and well-known music, Adiós Nonino/Quarteto Amazônia Toca Astor Piazzolla (1991), the group documented in the same 12 months two CDs inside a jv between Brazil, Austria, and Croatia; one of these focused on Brazilian composers documented at ORF (Austria’s Condition Radio and Television company), like the “Quarteto No. 3” (Alberto Nepomuceno), the “Sonata em virtude de Cordas” (Antônio Carlos Gomes), as well as the “Quarteto” (Alexandre Levy), documented for the very first time. In 2000, the quartet recognized its first Western tour with concerts in France, Germany, and Austria. Within the next 12 months, in the next tour, they performed in Rome, Vienna, Prague, and additional cities.
