In May 2023, SEÁN BARNA released a rock LP, An Evening at Macri Park, on the iconic indie label, Kill Rock Stars, to widespread critical acclaim from outlets such as NPR, Pitchfork, FLOOD Magazine, and Billboard. In their review of the LP, Pitchfork offered comparisons to Leonard Cohen, Harry Nilsson, and Rufus Wainwright, writing, "this is raucous, messy, and emotionally rich music, as any art about queer nightlife ought to be." In May 2024, he will release Internal Trembling, an EP of folk songs featuring the Nasville-based bluegrass supergroup, Hawktail.

Seán’s previous releases include, Pictures of an Exhibitionist (2014, LP), Margaret Thatcher of the Lower East Side (2020, EP), CISSY. (2018, EP), Cutter Street (2012, EP), and the single, “Straight Motherfuckers and Their Famous Friends.”

In 2021, Seán opened for Grammy- and Academy-Award nominated band, Counting Crows, on their 22-date national tour.
