For more than 15 years, Mr. Isengart has been at the forefront of international cabaret entertainment in New York City.
Starting out in the Mid-nineties, he was the first in New York to introduce trilingual cabaret shows that had a distinctive modern sensibility and look, fusing Weimar-era Kabarett repertoire and French chanson with American standards and contemporary pop music, paving the way for many to follow in his footsteps.
Isengart has performed his solo act Off-Broadway, in countless supper clubs and cabarets, multiple art museums and theater festivals abroad.
Isengart has been called the Darling of Café Sabarsky, the city's only established German Cabaret venue, where he has presented a record of over 9 different programs, including a highly controversial solo-version of Weill and Brecht's Seven Deadly SIns. He has also been a mainstay and star at the annual Museum Mile Festival on Fifth Avenue.
In addition to his solo work, Isengart has lent his Euro-cabaret style to multiple variety shows including Ami Goodheart's burlesque spectacular Rouge and Earl Dax's Weimar New York.
Isengart is the founder and creative director of Foreign Affairs, a multinational pop-up cabaret production that premiered as a speakeasy in 2008 and has since then had extended runs at the Gershwin Hotel, the Night Hotel, and the Griffin Night Club.
Lately, Isengart has taken on the unlikely repertoire of Elvis Presley, redefining the music and persona of the King of Rock 'n Roll and coming out triumphantly as what has been widely described as "The Weimar Elvis".
Isengart has created and directed countless cabaret shows at a range of established venues including the Museum of Modern Art, the Brooklyn Academy of Music, Feinstein's at the Regency, the Philadelphia Museum of Art, the Metropolitan Room, The Lensic in Santa Fe, and the Cleveland Museum of Art.
In the fall of 2012, Isengart performed Frankenstein!! – A Pan-Demonium by HK Gruber with the concert:nova ensemble under the baton of conductor Edwin Outwater. The piece was presented to high acclaim at the historic Emery Theater in Cincinnati.
