The siku is a wind instrument of Andean origin, highly symbolic in ancestral rituals, made up of two separate, complementary parts, the arca and the ira. It is a representation of duality, an essential element of the indigenous world view, associated with involvement and complementarity, far from the binary thinking typical of western societies. That duality is reflected on this record in the coming together of sounds, whether electronic or organic, past or present, local or global.
On Siku, Nicola Cruz combines instruments with symbolic, spiritual connotations, such as the sitar, the siku, and the balafon with hints of electronica. Studies of the samba, cumbia and rhythms of African, Andean and Hindu origin are combined with Cruz’s characteristically unpredictable, mystical style.'
