This just in: when I tested the link above, I saw on the home page that tonight they're rebroadcasting the Beethoven 6th and 7th, under the baton of Lorin Maazel, in a performance (or composite of performances) given in late October. You can catch the stream at 8:00 p.m. EST this evening, December 26. Again, the Globe critic wasn't satisfied, but I enjoyed it.
This is also the time for Bach's Christmas Oratorio — six cantatas for six days of the Christmas season. I'm a day late recommending that you listen to them, since the parts are designated for the first, second, and third days of Christmas (yesterday, today, and tomorrow as and where I write), for New Year's day, the following Sunday, and Epiphany (January 6 in the traditional calendar). They're worth listening to, even all at once, but probably better if you spread them out.
Here's a video of the opening chorus of the first part , the part for the Christmas Day. And an older video (slightly out of sync) of my favorite number, the bass aria, "Grosser Herr, O starker König." You can compare the qucker tempo and natural trumpet version with John Elliot Gardiner (same performance as the opening chorus I linked) if you want. YouTube gives a link. I actually prefer the Gardiner performance, but I wanted to give a sample of a slightly different performance style; and Fischer-Dieskau is one of the great baritones of the 20th century. I won't try to find videos of the whole thing, but I'm sure you can find most, if not all, of it if you want to. And I'm sure there are audio recordings available for downloading. I have three complete sets on vinyl discs, one led by Karl Richter, one led by Nikolaus Harnoncourt, and one featuring the Regensburger Domspatzen. Any of them that you can find would be worth listening to IMO.
