To be fair to the National Symphony this current season they had offered an all Mahler "mini-package" of all three concerts with Mahler symphonies. I jumped at that, of course. Why they did not repeat the experiment for 2011-2012 (of course this time for a different composer, or style of music) I don't know. They are doing last minute "half-price tickets" through the local half-price ticket vendor, but I like to plan ahead and not wonder whether or not a concert I'm interested in will offer discounts (the subtext through all this is that I'm on a limited budget).
