The Metropolitan Opera - Live in HD

The Metropolitan Opera presents their performances in the United States, Canada and Internationally via their Live in HD program.  Operas are shown at theatres, in full length, usually starting at 12:55pm EST on Saturdays during their concert season which runs from late September to early May.  Encore performances are also in theatres, generally on Wednesdays at 7pm throughout the year.

Another alternative to the Live and Encore programs in theatres, is the subscription based Met Opera on Demand where you watch past performances via your computer.  I tried a few of their sample feeds and they were very good, coming from someone who has not attended many (perhaps any) operas.  There is a 7 day free trial to view all operas in their library, then a subscription costs $15 per month.  Individual operas can be purchased at $4 and $5.

There is one presenting theatre in New Jersey at Monmouth College. The Live concert season is now over but there will be Encore presentations until the new seaon begins. Tickets at Monmouth College are $18.
