Andrew Lloyd Weber’s first-ever publicly performed musical is still one of his biggest crowd-pleasers, a colorful twist on the Old Testament tale of Joseph – a boy blessed with prophetic dreams whose father gives him a dazzling, multi-hued cloak. Green with envy over the gift, Joseph’s brothers sell him into slavery, and Joseph eventually ends up in Egypt, where he manages to rescue the country from famine, with a little help from Pharaoh (hilariously portrayed as Vegas-era Elvis). A multiple Tony nominee when it first appeared on Broadway, this feel-good show boasts a mix of musical styles, ranging from country and pop to rock and even calypso. Now a talented young cast from Phoenix’s Valley Youth Theatre brings this rainbow rollercoaster of a musical to the Herberger Theater Center stage.
