As the High Priest in Samson et Dalila:

“Rucker's High Priest was a standout performance. He declaimed his part so well he actually outsang Dalilah in their duet, which is hard for a baritone to do.” - The Oregonian

“Dagon High Priest Mark Rucker sang with forthright tone and was most effective in the second act duet with Paunova.” - Opera Canada
