Set in Ancient Greece, “Irrational” explores the original cult of personality - the Pythagoreans, led by the charismatic mathematician, philosopher and... rock star? This rockin’ musical is inspired by the true story of Pythagoras and his fervent followers, who believed that divinity was found in the harmony of ratios. When one of their own discovers irrational numbers, he blows a hole in their worldview and crosses the wrong mathematician.
