Orkater, Via Berlin and Ragazze Quartet together made special music theater performances at theater festivals. With ‘Lost Tango’ they celebrate the 10th anniversary of Via Berlin, now for the first time in the big theatre hall. The ambiguity of the tango, with its history of poverty, homesickness and glamor, is deployed in its full wealth. Ragazze Quartet is supplemented for this anniversary performance with the famous tango trio by Carel Kraayenhof. String quartet and piano trio together form a septet – a common composition for tango. In Lost Tango, two variants of the tango determine the atmosphere: the modern-classic ‘tango nuevo’ by Astor Piazzolla and the contemporary ‘tango rupturo’ by pianist and composer Julián Peralta
