The Cincinnati Symphony is trying to boost ticket sales with promotions meant to make the organization seem edgier and more in tune with today’s young adults (for instance, what 20-something wouldn’t love a temporary tattoo that says, ‘Get Your Beethoven On’?). This kind of thing rarely works, of course, but as long as the CSO is determined to try it, Chuck Martin has some additional suggestions for achieving hipsterdom. For one thing, concert halls need to be a far more nacho-intensive environment. For another, CSO music director Paavo Järvi is just crying out for a nickname, something like… ohhhh, how about P. Diddy?
