As the Count in Il Trovatore:

“But Mark Rucker's full-throated Count di Luna was the only notable plus in the cast...Rucker displayed a dark lyric baritone that took 'Il Balen' in supple stride, and he also gave a manly impersonation of the malevolent Luna.” - Miami Herald

“Mark Rucker made a convincing Count di Luna.” - Opera News

“Mark Rucker's Count di Luna exhibited a fine sense of Verdi Style.” - Musical America

“As the villainous Count di Luna baritone Mark Rucker is excellent. Given leisurely support from conductor Dejan Savie, Rucker turns in a characterful Act 2 Il Balen.” - Sunday Times (Ireland)

“Mark Rucker is a quite powerful Count.” - Irish Times

“Baritone Mark Ruker, cast as Count di Luna, demonstrated why he is such a favorite. He has the power, range and comfortable tone to make his dramatic delivery effortless – or seemingly so – while at the same time, managing to make one empathize with his sometimes unlikable character’s plight. It was a strong performance worthy of the equally strong approval from the audience received at curtain.” - OperaOnline

“Rucker was somthing of a marvel, particularly how he sustained long lyrical lines, such as in his aria "Il balen del suo sorriso." with a modicum of effort. His dark-hued voice ich without getting barky, was the most consistent pleasure of the evening.” - Hartford Courant
