To open the Boston Symphony Orchestra's 2013-14 subscription season, revered German-born conductor Christoph von Dohnányi is joined by violinist Augustin Hadelich in his BSO subscription series debut and cellist Alban Gerhardt for Johannes Brahms's Double Concerto for violin, cello, and orchestra, the composer's final orchestra work. Brahms's Symphony No. 2 dates from the previous decade. Composed relatively quickly after the composer's long-awaited First, the lilting No. 2 is generally regarded as the most genial and relaxed of Brahms's four works in the genre. Opening Night includes a pre-concert reception at 7PM.The page, linked above, provides further links to audio previews and to the program notes from the program booklet. In addition, there are brief bios of the musicians which you can see by brining your cursor over their pictures, and complete official bios by clicking on said pix.
As usual, it will be broadcast and streamed virtually live by Classical New England. The official starting time is 8:00 p.m., Eastern Time. Beginning at 7:00 they have pre-concert features, consisting mostly of music composed by the evening's composer or performed by the evening's performers. They also have a page of their own devoted to the BSO broadcasts with the season schedule and links to their own related material.
Last year they rebroadcast/streamed the concerts at 1:00 p.m. on the Sunday 8 days later. I don't notice anything about it right now, but I wouldn't be surprised if they do so again. I'd be disappointed if they don't, but so far it isn't included in the regular weekly schedule page.
