In 2001, in a public letter, the Mayor of Berlin, Klaus Wowereit, publicly welcomed the two Brazilian musicians when they presented a recital at the Berlin Konzerthaus. In 2004, the Mayor of Bremen, Henning Scherf, repeated this act when the concert "Disenchanted Amazon" was presented in the Bremen Municipal Government Palace. In the German edition of Wikipedia, Renato Mismetti appears in the list of famous classical music singers. Recently, based on the famous text by Antônio Castro Alves, "Navio Negreiro", the composer Siegrid Ernst, wrote "Memento" in which Renato Mismetti and Maximiliano de Brito, together with other musicians gave the first world performance with huge success. Mismetti also develops great interdisciplinary projects involving various art aspects and fields. In recognition of his cultural exchange activities covering various countries, the Apollon Foundation of Bremen, Germany, was included as an associate member of UNESCO's IMC – International Music Council.
