According to creator and star tenor Karim Sulayman, UNHOLY WARS, a 70-minute opera pastiche that made its debut on Saturday at Philadelphia Opera’s O23 Festival, “stitches together a collection of baroque music centered around the Middle East and the Crusades, examining the separation of the human race based on creed and color.” The result was a creative multi-visual/musical work with dance, drawing heavily on Monteverdi’s IL COMBATTIMENTO DI TANCREDI E CLORINDA, supplemented by Baroque arias and modern electronic music.
