As “Pleiades” they collaborate with various contemporary artists aiming to explore the connection between oral polyphonic vocal tradition and neoteric ways of musical expression. Their collaboration with Kostas Vomvolos and Kostas Theodorou, as well as with the Art Theater Aktis Aeliou has broadened the group’s vocal horizons. In 2011, «Pleiades» wrote and interpreted the music for the play «Berlin Alexanderplatz» based on Alfred Döblin’s book, for the Art Theatre Aktis Aeliou, and in 2012 sang two songs by Paris Paraschopoulos for the play «What you desire the most», by Dimitris Dimitriadis.
