Yes, we saw the National Symphony in D.C. a few years back. It was a family concert they were giving... we just happened to be there that day. Tix were $5 instead of the normal $30 for the worst seats. I won't go so far as to say the National Symphony is one of the best, but they're decent.
They played Stravinsky's Firebird Suite - oh, how I love that piece. Stravinsky is one of my favorite "modern" composers (I'm a big fan of abstract music, hence the crush on bands like Dream Theater).
Next was Saint-Saens' Carnival of the Animals. Now this is something I've loved since I was little. We had a record of this, and I listened to it all the time. My brother and I were sitting next to each other at the concert, and we were just cracking up when they played "Cuckoo in the heart of the woods". I know that sounds terrible, but it IS supposed to be a funny piece.
Then my favorite... Mussorgsky's Pictures at an Exhibition. This is another of my favorite symphony pieces, and they played it almost perfectly. It's a beautiful piece on cd, but hearing it in concert just gave me chills. I sat with goosebumps on my arms and legs during the whole piece.
I think I've mentioned before that I have season tix to the St. Louis Symphony Orchestra also. Most looking forward to: Orff's Carmina Burana (with the St. Louis Symphony Chorus and Children's Choirs); Mussorgsky's Pictures at an Exhibition (again!); Tchaikovsky's Swan Lake (which I saw at the Peoria Symphony Orchestra in middle school); Berlioz' Symphonie Fantastique (my parents are coming out for this one - it's on Halloween - how appropriate lol - this is probably my dad's favorite classical piece ever, and he just about went into shock when I told him I could get them tix for it); Handel's Water Music (I, II, and III); Strauss' Don Juan; and to top it all off, Stravinsky's Rite of Spring (which sadly I cannot listen to anymore without thinking of Disney's Fantasia - damn corporate America).
Of course, none of this even compares with what I'll feel on April 3 - Itzhak Perlman is conducting. If we're lucky, he may play also, but I'm trying to not get my hopes up. I have always wanted to see him conduct or play in concert, and missed several chances. So you can imagine how I'll feel that day
