Kristine Levine

“It’s debatable whether honesty makes for the best comedy, but Levine certainly makes a damn good case for it being so by telling stories and observing motherhood, romance, and the oddities of life with the only filter being that it’s undeniably hilarious.”
The Comedy Bureau

“Stark and unapologetic dispatches from an exotic life.”
The Guardian

“One of the few comics who doesn’t seem to gather her material via her remote control… Lucky crowds had their sensibilities challenged, tested and happily bruised, black and blue.”
The Oregonian

“Wonderful back-to-basics, take-no-prisoners stuff.”
The Scotsman

“One of the most original comedic voices of this generation.”
Doug Stanhope


Landry’s most notable attribute lies in his charming hair, which emanates from his charismatic follicles. As a Canadian-born individual of interracial heritage, his unique existence, coupled with a touch of dysfunction, creates a delightful blend of comedic brilliance. He has earned prestigious accolades such as the Boston Comedy Festival and the World Series of Comedy, but the ultimate measure of his success remains the approval and amusement of his beloved mother. With a radiant smile that illuminates any space and a personality that perfectly complements it, the potential for Landry to accomplish extraordinary feats as a performer is boundless.
