On tonight’s (April 30) semi-final episode of ‘The Voice,’ resident opera singer Chris Mann chose to sing ‘Ave Maria,’ in a move that showed he would be staying true to himself when everyone is watching his moves. He sang a Coldplay song during his last performance and while we loved seeing (and hearing) him go pop, he smartly returned to his wheelhouse, which is a big, bold, beautiful song sung in another language. It’s the semis. You go big or you go home. Mann chose to go huge, really.
