BSO Assistant Conductor Marcelo Lehninger leads the orchestra in Mozart's Sinfonia concertante, K. 297b, featuring BSO soloists, Bachianas brasileiras No. 5 by Villa-Lobos, with soprano Nicole Cabell, and Beethoven's Symphony No. 5.(Emphasis added.)
That page also has a link to a conversation with Maestro Lehninger and a preview of the concert. In addition, they give the concert broadcast and webstream schedule for the whole upcoming BSO season. I'm happy to see that they'll again be replaying each concert on the Monday nine days later.
My post about it at the time (with links to reviews and the BSO page) is here. I put a question mark after Mozart's name because the program notes say that some scholars doubt that Mozart actually wrote the piece in question.
