Marcus Shea serves as the host and photographer behind the Performance Anxiety podcast, an interview-driven series focused on the creative hurdles and mental landscapes of professional musicians. Operating within the Pantheon Podcast Network, Shea utilizes a background in professional photography to create visual portraits that accompany his long-form audio discussions. His work includes deep-dives into alternative rock history, featuring technical and emotional insights from legacy members of bands such as Soundgarden, Pearl Jam, and Bauhaus. A recent hallmark of his content is the multi-part Spinal Tap Tribute series, a collaborative project that brought together global rock icons to raise support for Teen Cancer America’s Play It Back program. By bridging the gap between an artist's public persona and their behind-the-scenes reality, Shea provides archives for indie and alternative communities. His episodes often uncover untold histories of the D.C. punk scene and the evolution of sub-genres like Cajun black metal, proving his role as a music documentarian.
