"Habanera" from G.Bizet's "Carmen" is a true masterpiece. Please, enjoy mezzo soprano Elina Garanca's performance and give my version a listen, too. 

Aria of Rosina from G.Rossini's "The Barber of Seville".
The original version is performed by fabulous soprano Edita Gruberova, while I suggest a new jazzy approach :)

Fabulous "Air on G String" from J.S.Bach's Suite No.3 is one of this compositions which, once heard, would be memorized and cherished deeply in ones heart. I love it so much that just couldn't resist to sing it!

Aria of Nemorino from G.Donizetti's "The Elixir of Love" is one of the highlights of the tenor repertoire.
Please, admire Pavarotti's art of interpretation and take a look at mine :)
