Much more eclectic. Vocal, instrumental, orchestral, interviews, narrated programs, in any combination. Old music, new music, and everything in between, including, believe it or not, rock & roll! (In a historical study, you see).
At the risk of upsetting BR,
here is the link. For instance, as an example of their eclecticness, they have a "what if" program. "What if" something trivial had or hadn't happened? Yesterday's program was on Verdi. What would have happened if he hadn't met his agent while going shopping, and gone to his office with him to read the libretto of "Nabucco"?
All it would have taken to upset operatic history, and deprive OT of some wonderful high Cs, was a loose shoelace. If GV had stopped to tie it up, he'd have missed his agent and never seen the libretto.
The program put forward an alternative history, with lots of excerpts from GV's music, and occupied an interesting hour.
