If you’re outside Middle Tennessee (or, for that matter, if you’re inside Middle Tennessee) check and see if your local public TV station will carry “Gershwin at One Symphony Place,” an edited version of a Gershwin concert by the Nashville Symphony which aired live on WNPT last September. I love Gershwin, and I love the Nashville Symphony, and I loved the original concert, which PBS stations nationwide will carry — many tonight, others at various times over the next month.
