This production, while difficult, is beautifully cast, and an important message about the responsibilities faced by those personally involved in the Manhattan Project. I do not think I will soon forget the final comments by Jeremy Kushnier (Leo Szlard). I particularly liked the performances by Jonathan Hammond (Enrico Fermi) and Randy Harrison (Paul Tibbets/Edward Teller). Warning…this is a production that depends on the use of very bright flashing lights (after all, it is about the making and the dropping of the atomic bomb). The music, though billed as a Rock Opera, is not overwhelming and really quite good.
