I feel lucky to have the CPO around and they are a brilliant group of musicians that attract a lot of talented guests and special programs.
If you are under 29 you're super lucky and have the opportunity to see many of the amazing shows for $15 for you AND a another $15 gets you a guest of any age and often you're getting some pretty nice seats out of the deal (unlike many other youth or student programs). You just have to register for cpossibilities on their website and you'll get a monthly e-mail about the shows you can get cheap tickets for. It takes a bit more planning ahead but it's worth it as probably 80% of the concerts open up for cposs. This is a program I liked (when I was young enough *sniff*) because I needed to get out of school before I could justify even that $15 for a night out but it allowed me to get involved and fall in love with music without the largish investment. Since music was not a large part of my childhood, that connection was something CPO did for me from scratch in my mid to late 20s. There are plenty of youth targeted shows .... superheros, star wars, star trek, bugs bunny, Nightmare Before Christmas, fantasia, ET, circus acts... these type of shows were gateway concerts for me into some more of the classics but it was nice to start with music I knew well from the movies.
I think the only caution would be you may realize you are like me and have 11 CPO concerts in a season (after you're no longer getting cheap tickets but have development a taste for the good seats) and you only have 2 saddledome concerts in that same time frame. It makes me feel like I'm suppose to be a grown up or something now.
