Typically these are concerts available to regular subscribers in packages, hence the "Subscription" category.

Once they become available for sale, the webpage on which the concert is listed will be updated to include an online button titled "Choose Seat and Cost".

You can see that button at the bottom of this page: http://www.cso.org/sat_performdetail.taf?eventid=4095

Clicking on that, takes you to a page where you can choose the number of tickets you want, the seats, etc.

From what I've been able to see so far, because regular series subscribers pay a lot of money in advance, they simply get an earlier opportunity to reserve tickets.
Tickets for the 'general public' typically become available a month or two later.

Note that for the Williams concert, they don't even have the program up. http://www.cso.org/sat_performdetail.taf?eventid=5115

And to answer Lou's question, Williams is doing three concerts in Chicago in November (unless something changes). The first one is on Friday, November 28, and will apparently be Williams conducting selections from a variety of "Movie Music Classics." The other two concerts are on Saturday, November 29, and Tuesday, December 2, and both of those will apparently be all-Williams concerts.

I'm going to try to go to two of them (the classics program and one of the all-Williams programs), but it'll all come down to money, I suppose. I saw Williams with the CSO in the summer of 1999, and I'm looking forward to another go.

But I'm only 3 hours away, so it's a quick drive.

Heck, if I can jump in a car at 7:30 at night, and drive straight until about 40 miles from the Mississippi river to see a stupid meteor storm (which didn't show up), and then drive straight back home, I think I can make Chicago.

If I have money.

Just so you know, you are not alone in your dilemma. They're doing the same thing here in Pittsburgh for his concerts with the Pittsburgh Symphony Pops in June, I believe.

Suite from Star Wars
Suite from Harry Potter
March from Raiders of the Lost Ark
"Flight to Neverland" from Hook
Theme from Jurassic Park
Theme from Jaws
Two pieces from Superman
"Adventures on Earth" from E.T.

But the REAL pièce de résistance is the other two concerts:

Saturday, November 29, 2003, 8:00 PM
Tuesday, December 02, 2003, 7:30 PM
Concert music; music for film
Concerto for Horn (CSO Commission, World Premiere)

I should be buying my tickets for the Friday and Saturday concerts in the next few days.

Who else is going?

NP - Zoo Caprices (Michael Nyman)

A "Grand Suite" from Star Wars with James Earl Jones as narrator featuring music from all five Star Wars films will make it´s debut there, JWFan reports.

I just got my tickets for the November 28th performance today. I don't subscribe because I live in the suburbs and I don't think I could make it downtown often enough to make it worth it (though I would love to). I also bought tickets to a concert where the CSO will be premiering a new commission from Lalo Schifrin. It's coupled with the Symphonie espagnole by Edouard Lalo...I wonder if Schifrin gets that a lot.

So not being one to go downtown too often, I don't know about the best places to meet up. What do you recommend?

I'm still planning on going to one of the other concerts, but I'm trying to coordinate it with a few other friends, so I haven't bought tickets yet.
