Hashtag Ensemble – music cooperative specializing in contemporary music, improvisation and musical education, established and managed by flutist Ania Karpowicz.


Members of the cooperative are young Polish musicians: composers, vocalists, instrumentalists and a conductor from leading cultural institutions such as Sinfonia Varsovia Orchestra, Polish Radio Orchestra, Polish Royal Opera or The Fryderyk Chopin University of Music.
Hashtag Ensemble cooperates with composers and has ordered new pieces from Jagoda Szmytka, Artur Zagajewski, Agnieszka Stulgińskia, Adam Porębski, Paweł Malinowski and Zygmut Krauze, among others. It has in its repertoire classical works of 20th century music, by Peter Maxwell Davies, Louis Andriessen, Helmut Lachenmann, George Crumb, Gérard Grisey, Steve Reich and others.
Hashtag Ensemble operates by creating egalitarian structures based on multi-layered activities of its members and by building programmes based on legible and usually non-musical contexts. An important element of the group’s concert practice is support and presentation of artistic achievements of women – since its beginning the group has co-operated with multiple female composers and artists.
The group has performed at numerous festivals, has been hosted by prominent concert halls, but also music clubs. Hashtag Ensemble performs finalists’ compositions at composers’ competitions.
