The cast features F. Michael Haynie (Wicked, Holler If You Hear Me) and Sarah Beth Pfeifer (Legally Blonde, The Lightning Thief).
With music and lyrics by Rob Rokicki and book and additional lyrics by Michael Ruby, Relativity is described as "an exciting, funny and poignant new pop/rock musical about siblings and perspective. The show follows the characters Derek and Reagan, twins who discover over the course of a decade that there are two things no one can ever escape: time and family."
The evening is directed by Paul Stancato. Musical director Rokicki leads a band that includes Micah Burgess, Seth Eliser and Dennis Michael Keefe.
