For Henry Cow his most famous is possibly Leg End (aka Legend) from 1971. I'm not sure he's normally put under classical though, it's more an experimental mix of things.

Thanks, but I can't seem to find it on Youtube. Anyway, I heard some of his other music and I don't think much of it. Do you have any other suggestions?

I was actually replying to someone else. :D

For some triumphant music, something like this, Walton - Crown Imperial.

I don't understand why Henry Purcell is not universally regarded as one of the truly great Baroque composers. Maybe he's popular in the UK and other countries, but here in the US, it seems that the stations never play him. I'd never heard of him until a few years ago when I listened to a King's Consort CD with Purcell's "O fair Cedaria" sung by Barbara Bonney. The song came to me from time to time, but I forgot the composer's name. Recently, I discovered two Purcell operas, Dido and Aeneas and The Fairy Queen, which is based on A Midsummer Night's Dream. There are You Tube excerpts from both operas. In particular I recommend excerpts from The Fairy Queen performed at Glyndebourne Festival, conducted by William Christie. Purcell is sublime and earthy. "Come away, fellow sailors" in his tragedy Dido and Aeneas may be unique in Baroque music, a number about drunken sailors on shore leave.

I love Purcell's music, and I think he was just overshadowed by more popular composers during that time, like Bach and Handel, for instance.

Thinking of looking into Schoenberg, and thinking of giving Webern another chance. What would be the densest, and bizarre of their works?

Thank you.

The first opera I have liked is Cosi Fan Tutte.
I still haven't listen to the whole opera yet,but would like to hear suggestions for a second opera to listen to.

Marriage of Figaro if you don't know that.

Thank you! :)
