Joshua Bell shows up a fair amount in the Bay Area, but let’s not get blasé about that. A Bell concert is still a good reason to bestir yourself to get tickets and make a trip. Sacramento Valley residents should be particularly pleased that the violinist is showing up at the Mondavi Center with the Franck Sonata, the Prokofiev Second Sonata, and a few more works to be announced from the stage. Normally, you’d have to drive into San Francisco for such an enchanted evening. As it is, the recital is so high-demand that you’d better drop everything right now if you want a ticket.
