Mixing classical and contemporary sound, Mario Batkovic seeks to explore the sonic possibilities of the accordion, without effects or loops, rather through a mutualist symbiotic relationship between man and instrument. 'INTROSPECTIO' is a self-questioning, self-examination of society and the meaning of sound. Featuring collaborations with electronic sorcerer James Holden and former BEAK> member Matthew Williams aka MXLX, in addition to drummer Clive Deamer (Radiohead/Portishead/Robert Plant/Roni Size), saxophonist Colin Stetson and concert choir Cantus Domus, Batkovic questions the place of sound, clichés and prejudices, taking the listener on a journey through infinite universes of sound.
