Shimmer Boy

Shimmer Boy is the indie project of Cork songwriter and guitarist Aaron O'Sullivan, blending folk, alternative rock and heart-felt songwriting. With 15+ years of experience as a working musician, he is quickly building a name as one of Ireland's emerging independent artists.

Following the release of his debut album In The Aftermath, We Bloom, Shimmer Boy has picked up strong momentum across radio, television and live performance. "Hideaway" earned RTÉ 2FM Track of the Week and Radio Recommended recognition, while "Faith In You" marked his television debut on RTÉ One. His music has also reached an international audience through a sync placement for "Under The Surface" in the UK series Made in Chelsea.

In 2026, Shimmer Boy performed at Electric Picnic, sold out his headline show at Cork's Coughlan's, and was selected as 96FM's Local Hero in association with Hot Press. He has also shared stages with Dave Lofts, Oscar Blue and Robert Grace.

With a growing catalogue, national radio and television support, international sync experience and a rapidly developing live profile, Shimmer Boy is carving out his own space within Ireland's independent music scene.
