There is no Harold Martin Tillmann, no cousin or brother to Sean Tillmann, to help with his artistic output and press coverage. First was the art-school noise-pop trio Calvin Krime, which split up in the summer of 1998. Sean went his own way and created the introspective indie dreamboat Sean Na Na. After a few years, Sean created another stage persona named Har Mar Superstar. Named after a Minneapolis-area mall that was built in 1961 and fell into disrepair, Har Mar is the sexy-smooth R&B artist who has grabbed the most attention for Sean Tillmann.
