Kostas Hanis was a founding member of “Diotima” and the percussion quarter “Nakara”. In the recording album published by Diotima, he created 5 original compositions infused with ancient greek rhythms and traditional sounds, with the use of various percussive and wind instruments.
Composition started playing an important role for Kostas from the moment he could utilize percussion as a comprehensive set of performing orchestral music, by experimenting with the power of the natural complexion of percussive instruments and icorporating the classical form/style in works for percussion. He is using a wide variety of percussive instruments such as flower pots and mortars, that are producing clear and melodic sounds.
