XelmYa ( Alexa Renger - violin, Sylvia Hinz - recorder, Ehrengard von Gemmingen - violoncello ) was founded in 2008.
One of their goals: to push, foster and develop the instrumentation of the baroque trio sonata into contemporary music and modern times. Since their formation they performed numerous premieres composed especially for this trio. They also perform rarely known pieces.
The promotion and fostering of contemporary music is one of the main topics of XelmYa. Sylvia holds contact with numerous international composers and develops concepts and programmes for concerts, realised at e.g. the festival “Klangwerkstatt Berlin“ or the concert series „unerhoerte Musik“. Exceptional: the project “CONTEMPORARY BACH!” Excerpts of „The art of Fugue“ by Johann Sebastian Bach, performed contrastive with contemporary pieces. The plans for the near future include premieres by Petra Vermote, Maxim Kolomiiets, Louis Aguirre, Gunnar Karel Másson, Massimiliano Viel, John Strieder and others ... and the MEDEA GENDER PROJECT in 2015!
