Clue: It's well known that this (famous, revolutionary) ballet (ballet 1: 4 words, 2, 5, 2, 9) by (composer 1: 9) incited a riot during its premiere at (location: 7, 3, 6-7 (typically hyphenated)).

However, it's perhaps less well known that this (much less known?) ballet (ballet 2: 6) by (composer 2: 5) also incited a riot during its premiere. The famous artist (7 letters) apparently collaborated with the composer on this ballet.

Provide
1. Ballet 1
2. Composer 1
3. Location of premiere of ballet 1
4. Ballet 2
5. Composer 2
6. Artist/collaborator of Ballet 2

Letter hint: 2nd letter of Composer 2 is "a."

Sorry, composer 1 has 10 letters. But this part of the clue is so easily Googled anyway.

The first part is:
La Sacre du primtemps (The rite of Spring) - the fact that you're looking for the French title stumped me for a while.
Stravinsky
Théâtre des Champs-Elysées

The second part I'm not as sure. This comes to mind:
Ravel
Bolero
Not sure who the artist was.

Part 1 is correct, of course -- just a minor thing: I think it's "Le sacre" rather than "La sacre."

Is "Bolero" a ballet?

Actually I've never ballet 2 before and I was quite surprised when I read about it.

I'll give you a hint. Composer 2's works are frequently full of instructions regarding how they should be performed, and some of them have very funny names. One of his works is so frequently played that even if you don't listen to classical music, you've probably heard it many, many times. His reputation has probably declined since his death. You'd know his name, for sure, but you might not think of him as a great composer.

And to be a little clearer, that piece you must have heard countless times is a piano piece.

Well, I'm not sure if I really have heard of him (vaguely familiar), and I don't know which piano music you have in mind (the only piece of music that came to my mind was Pachelbel's Canon).
Anyhow, I think this is what you're looking for:

Satie
Parade
Picasso

BTW, sorry about the "le". I know that's an insult to someone who knows french, but I only slept for 4.5hrs and my brain doesn't work well without enough sleep!

Maybe his Gymnopédies No. 1?

My French is pretty bad, but accuracy is important.

You can't be so addicted that you're playing even with lack of sleep?!

But yes to the rest! And I'm sure that you've heard Satie's Gymnopedie before. Just download it somewhere and you'll know what I mean. It's very famous.

So next clue?

By the way, Satie seems to be enjoying some sort of renaissance. The French pianist Jean-Yves Thibaudet (he made a cameo appearance in a Met opera, I believe, and likes to wear red socks) recently released a set of Satie's piano music.

My neighbor is renovating their house, so it's impossible to sleep much with all the construction noise. I don't have to work for the rest of the day, so it's ok.

Next clue. Staying on the music thread, though quite a change of direction from classical music:

This eccentric (at least to me) singer (name: 5,14, but s/he only goes by the first name, in which "r" is the 4th letter taken from "Parade" ) from (city: 9 & country: 7) recently released a new album (title: 7). The album is unusual as it has no instruments in any of the songs, only vocalists.

I'm shocked at myself that I probably actually know this.

Did you miscount?

It's 5,15, yes, for the name?

Ok, nevermind.

I may as well answer this one:

Bjork
Gudmundsdottir

Rekjavik, Iceland

Medúlla

Did you know that Matthew Barney fathered her child?

G u d m u n d s d o t t i r
I'm pretty sure that's 14.
I guess I missed her performance at the Olympics. I still cannot get over her "swan" dress couple of years back...

Yeah, initially a Google search said she was someone else's daughter. Sorry about that.

Needless to say, I've no concept whatsoever of what her music is like, but I guess some of it was used in "Dancer in the Dark."

Clue: You may think this artist (7 letters, 2nd = "o&quot is American of some famous paintings on (objects: 2 words, 8, 5), but he is actually of this nationality (7 letters).

Hint: Proposed a controversial theory a couple of years ago that has since been largely discredited.

Sorry, you may think the artist is American *because* of....

David Hockney?
Swimming pools?
British

Yes, very good.

He proposed the theory that artists used lenses to construct remarkably accurate paintings, but there have since been a few rebuttals.

This person (7,7), though American (I believe), is a/an (job title/profession: 11 letters, 2nd letter is "c" from Hockney). His job has something to do with new concert halls.

My guess would be Russell Johnson, acoustician:
