Namely, it should go without saying, safe computer-generated public domain Beethoven. I'm not advocating paying for audio of shaky Karajan strings or going to a Berlin Phil concert. Supporting your local classical music bands is more understandable. If you do go to a Berlin Philharmonic concert, maybe make sure it's Emmanuelle Haim conducting. I don't agree with all her artistic decisions but she can make them play actual music rather than their traditional Furtwängler-style dirge.
