About
THE OLLLAM is a transatlantic collective that blends Irish traditional music with Detroit’s psychedelic post-rock energy. 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)
- Joe Hettinga (keys)
Their sound is deep, rhythmic, and melodic—rooted in tradition but reaching into bold, cinematic territory.
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. On the road they invited audiences to join them at local Irish pubs for a “Trad Session” where fans could jump in and play with the band. The chaos was documented and shared online via @theolllam.
Following their acclaimed 2022 album elllegy, which earned RTÉ Radio 1’s Best Group, and with an international fanbase, THE OLLLAM are on a mission to redefine the boundaries of Celtic and post-rock music.
After the 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 lineup that included John Mayer, Maren Morris, Elley Duhé, Julia Michaels, and Bea Miller.
