Tenors are considered by many audience members as the 'glories' of opera. What they do seems beautiful, athletic, stunning and unreasonable, all at once. Well, we have some wonderful tenor roles this upcoming season: Tonio in The Daughter of the Regiment, Samson in Samson and Delilah, and Radames in Aida. Tune in as Nicolas Reveles, the Geisel Director of Education and Outreach opens up the world of the operatic tenor in this week's installment.
