Murnaghan is a multidisciplinary artist working with the substance of belief, fragmentary points of intersection between the spiritual, scientific and psychological. Projects rarely happen without other people and the generosity of exchange. Whereas his physical exhibitions often foreground video, sound and sculptural installation, he is interested in expanding the platforms where concepts are shown, resulting in works on Channel 4 T.V. (London), in an abandoned Soviet Army barracks and the subconscious minds of a captive audience. Solo exhibitions include 'All Mountains Are Moving', at Limerick City Gallery, and 'Penumbra' at The Royal Hibernian Academy and most recently, ‘Split the curlew and you’ll find the music’, at Linenhall Arts Centre. Group exhibitions include, TULCA 18, ‘Melancholy in Progress’ the 3rd Biennial of International Video Art at The Hong-Gah Museum in Taiwan, ‘Blasphemy’ at The Oonagh Young Gallery in Dublin and Memorious as part of MOPE at The Kunsti Museum of Modern Art in Finland. Residencies include The International Studio & Curatorial Program in Brooklyn, Platform in Finland and The Bolay Residency at The Linenhall Arts Centre in 2023. He has exhibited in numerous international group shows, with solo shows in Finland, Estonia, Germany, USA and Ireland. Sound/music composition is central to his practice collaborating with artists such as Celina Muldoon, Sandra Johnston and Dalila Belaza. 'Long song dream' was selected by Pat Murphy for 'FREE FROM NEAR OR FAR' at The Irish Film Institute in Sept 2021. A small screen installation with a text by Murnaghan was on show as part of Sarah Pierce’s exhibition ‘Scene of the Myth’ at The Irish Museum of Modern Art in September 2023.
