Like its preceding Project PurPur, the Project EOS is based on the practical and theoretic exchange of knowledge of different playing, sound and performance traditions, that is the musical cultural heritage of a huge range of European states. It has now been expanded to include the dimension of opera. It also deals practically with the singing and performance tradition of European opera houses. This work is taking place under the support and guidance of the best singing coaches and orchestra musicians of Europe (members of the Vienna and Berlin Philharmonic Orchestras and the Milan Scala). At the centre of the Project EOS are two operas by Joseph Haydn: 2013 ORLANDO PALADINO, a “dramma eroicomico” in three acts (Hob. XXVIII:11) and 2014 L'ANIMA DEL FILOSOFO, OSSIA ORFEO ED EURIDICE, a dramma per musica in five acts (Hob. XXVIII:13). These two operas are being implemented with young, ultra talented European singers and orchestra musicians, integrated into the Orchestra Purpur, which is a sustainable result of the previous project. For each opera, the implementation is taking place in two workshops and two production phases. Concertante and scenic performances will follow at the five partners. The workshops will deal intensively with the themes of sound, playing and singing traditions and with the fundamental issues of mobility (support with visa, insurances, working permits etc.). The work programme of the Project EOS includes also an “audience development” initiative, which it is not just about retaining the public, but winning over new audiences for the art. Our programme focuses on children, young people and tourists! For the latter, we are expecting a twofold effect: We want to attract them back to their holiday destination - as some of our partners live from tourism - and we are “sending” them back to their homeland with valuable cultural experiences, which can enrich the cultural landscapes there. In this way, a new form of Europe-wide mobility will develop!
