maunderings of a meandering mind

If what you like is the commentary, most classical music concerts usually have a pre-concert lecture (given by the conductor and/or composer-in-residence who has a piece on the program) which is free and open to the public. It might take some doing to figure out which concerts have them and when exactly they're scheduled (usually it's about an hour before the concert itself) but you might find it worth it to start attending those. :)
