THE OLLLAM is a transatlantic collective that blends Irish traditional music with Detroit’s psychedelic post-rock energy. Their sound is deep, rhythmic, and melodic. Rooted in tradition but reaching into bold, cinematic territory. The band are playing a series of Irish shows in October, beginning in 3Olympia Theatre, Dublin on 5th October 2026, with special guest Múlú. Tickets priced from €37 including booking fee & €2 restoration levy on sale now with  Ticketmaster Ireland Led by John McSherry (uilleann pipes, whistles) and Joe Dart of Vulpeck (bass), the lineup includes Michael Shimmin (drums), Ross Ainslie (whistles), Seán O'Meara (guitar), and Joe Hettinga (keys). In 2025, THE OLLLAM embarked on their first full North American tour from coast to coast selling out venues across the country in major cities like Boston, New York, Chicago and Oakland. Bringing a unique flavor to the road the band invited audiences to join them at local Irish pubs for a “Trad Session” where the fans could jump in and play with the band. This created a one of a kind connection with their audience across the United States. The chaos was documented and shared online via @theolllam ! Following their acclaimed 2022 album elllegy , which earned RTÉ Radio 1’s Best Group.  With an international fanbase, THE OLLLAM are on a mission to redefine the boundaries of Celtic and post-rock music. Following their tour, THE OLLLAM appeared as special guests during Zedd’s headlining set on the Outdoor Theatre stage at Coachella 2025 , performing their collaboration track Sona from his album Telos . The performance, watched by millions, was part of a star-studded lineup that included John Mayer , Maren Morris , Elley Duhé , Julia Michaels , and Bea Miller . THE OLLLAM also recently shared the spotlight with rising Belfast actor Anthony Boyle ( Say Nothing , The Altruists ), who delivered a powerful spoken-word performance during one of their 2025 headline shows in his hometown of Belfast. From ancient airs to future soundscapes, THE OLLLAM are not just carrying the tradition forward, they're reinventing it.
