Mark Duplass began touring as a solo singer/songwriter in the 1990's. After a medical condition sidelined his guitar playing, he formally studied composition at City College of New York. Shortly after completing his studies, Mark formed Volcano, I'm Still Excited!! with Craig Montoro and John Thomas Robinette, III. The band caught the eye of, and eventually signed with, Polyvinyl Records. Volcano disbanded after touring in support of their debut release.
Duplass has since successfully pursued his career in filmmaking alongside brother, Jay, forming Duplass Brothers Productions. Mark and his wife, Katie Aselton, have also acted in a number of feature films and both star in the FX network's television series, The League.
