DANUBIUS OCTET SINGERS is a man's octet, composed out of professional singers - alumni of both of the conservatories and music colleges with primary focus on the interpretation of "a cappella" songs composed by the Slovak as well as the foreign composers of classical music. Individual octet's members are members of the leading choral ensembles (the choir of the Vienna State Opera, the Vienna Volksoper Choir, the Slovak Philharmonic Choir, the Slovak National Theatre Opera) in two of the capitals on the Danube - hence the name Danubius Octet Singers. The enseble was established in 2013 on the initiative of a conductor and a choirmaster Daniel Simandl and a member of the Vienna State Opera Choir Jaroslav Pehal to fill an empty space in professional interpretation of the male voice choir without an instrumental accompaniment in the Central Europe. The main objective of the octet's dramaturgy is discovering, public presentation and recording of the often forgotten treasures of the cultural heritage of Slovak national music, such as the songs of a master Eugen Suchoň, Ján Levoslav Bella, Mikuláš Schneider-Trnavský and other Slovak, Czech and Slavic authors who devoted large part of their work to male voices. The ensemble represented Slovak vocal art at international music festivals in Germany and the Czech Republic - "Mitte Europa Festival 2014" and on the International Festival "Janáček's Hukvaldy 2014" , in Budapest (2015), in Vienna (2016,2017), Festival of Male Choruses in Pécs, Hungary (2016) and Festival of Chamber Music "Konvergencie" in Bratislava, Slovakia (2017)
