Tillmann has gained international notoriety with his over-the-top live performances that often end sweat soaked and scantily clad. His wild stage antics and legendary singing prowess have landed him on tours performing with and opening for The Strokes, Red Hot Chili Peppers, Yeah Yeah Yeahs, Sia, Gossip, Lizzo, The Afghan Whigs, and Atom and His Package, to name a few. Armed with just a microphone, a mini-disc player, and a small canon of low-fi R & B songs in the early years, Tillmann earned fans through sweat equity. Now, Har Mar Superstar has become a six-piece, full-on soul review that plays the greatest hits of Tillmann's mind.
When not touring to support his albums, Tillmann can be found writing scripts and acting on both stage & screen. You may have seen him pop up in films & TV shows like Starsky & Hutch, Pitch Perfect, and Broad City. Always up for a new challenge, Tillmann is rarely found taking a break from a never-ending array of projects which has earned him his reputation as one of the hardest working people in show business.
