If you liked that excerpt, then by all means try the entire opera, Turandot by Puccini. If you respond to that style (I sure do) then try more Puccini, which is not a bad place to begin:
1) La Boheme
2) Tosca
3) Madama Butterfly
4) Il Trittico (especially Gianni Schicchi)
If you're still craving more, try more Italian:
5) Cavalleria Rusticana (Mascagni)
6) Il Pagliacci (Leoncavallo)
7) Il Segreto di Susanna (Wolf-Ferrari)
By now you should be hooked, and try some Verdi. Others are going to quibble and ask where's the Mozart and Wagner? My opinion: neither of those are suitable for beginners. Too long, and sometimes just plain boring. There are many wonderful, exciting operas that no one should ignore: Hansel and Gretel (Humperdinck), Schwanda (Weinberger), Sly (Wolf-Ferrari), Salome (Strauss), The Dead City (Korngold), Eugene Onegin (Tchaikovsky), The Consul (Menotti) and countless others. Enjoy. There's more opera than any one person can absorb in a single lifetime. So get started!
