Liam O’Callaghan, a graduate of DLIADT who shows with the Rubicon Gallery, has displayed an exceptional ability to make carefully orchestrated, cohesive sculptural pieces and installations utilising a bewildering range of different materials, including myriad found and discarded objects.

The artist shone during this year’s Dublin Contemporary, for example, with the wit and lively intelligence of his work. Now he goes for a piece of actual orchestration, as it were, with an audio-video installation comprising an agglomeration of turntables, amplifiers and speakers, “reconfigured and manipulated so as to autonomously perform a complex musical composition of looping records”. He has form here, often having used kinetic elements and sometimes, to great effect, sound.

Tucked snugly in the heart of town in the middle of the Christmas season, Bit Symphonypromises to be unmissable.
