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), and 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. 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.
