Chinese Australian composer Liza Lim was inspired by the lyric poetry of the Sufi poet Hafiz for her work Tongue of the Invisible. Lim explains, "the way in which he mixes and shifts levels of meaning gives rise to complex and indeterminable frames of mind in oneself." This variety of meaning is first and foremost reflected in the juxtaposition and coexistence of precisely and meticulously composed textures and improvised elements. But the compilation of the text set to music also facilitates numerous variants and interpretations. These dialogues are superbly "narrated" here by the pianist Uri Caine, singer Omar Ebrahim and the soloists of the ensemble musikFabrik.
