In Iron Mountain's music, Psychedelic, Kraut and Post Rock are joined with Irish Folk to create colourful instrumental songs that are, indeed, beyond words. The protagonists behind this Limerick-based band look back on years of artistic experience in different fields, floating from the spotlight of hit show "Riverdance" to being a band member of Canadian singer/songwriter Bruce Guthro (lead singer with Scottish Celtic Rockers Runrig) or live musician with many Irish folk artists, sought after composers of Irish traditional Flute music or even working on production in the Irish film industry.
