The Achill 400

Hailing from the rugged coastline of Achill Island, Co. Mayo, The Achill 400 are a high-energy musical collective that perfectly captures the "wild west" spirit of their home. Known as the island’s own "local rockstars," the band has carved out a unique niche by bridging the gap between Ireland's deep-rooted traditional music and the raw, electric energy of rock ’n’ roll.

The Festival Favorites

The band has become a staple of the Battle for the Lake festival (Achill’s premier music and watersports event). Sharing stages with national heavyweights like The Hothouse Flowers and Cormac Begley, The Achill 400 are frequently cited as a highlight for their ability to turn a local gathering into a full-blown stadium-style performance. Their ethos is best summed up by the festival’s own description of them:

"You know when you know! Finest Local Rockstars!"

A Proud Achill Identity

Deeply connected to the island’s culture, the band is part of a vibrant local music scene that includes acts like The Achill Sound and Graham Sweeney. While they lean into the rebellion of rock, their music remains an authentic expression of life in Co. Mayo—resilient, loud, and community-driven.

Whether they are playing an intimate set at the historic Valley House or headlining a festival main stage, The Achill 400 deliver a performance that is as unpredictable and exhilarating as the Mayo weather.
