Heisenberg Uncertainty Players (HUP) is a 17-piece new music ensemble with jazz big band instrumentation that is quickly becoming known as one of the most ambitious and creative ensembles in Chicago. Formed in 2011 playing exclusively original compositions and arrangements from founder and director John Dorhauer, HUP has performed original arrangements of entire albums by The Beatles, Led Zeppelin, and Heart and premiered a nine-movement multimedia suite inspired by destroyed baseball stadiums. HUP's 2020 release, "Gradient," is available on all major streaming platforms.
