Arcangelo Corelli didn't leave us with a great body of music, but several other composers of the Baroque took notice of his concerti. Francois Couperin was an admirer, and he wrote a tribute piece in his honor. J.S. Bach studied Corelli's music and he was an admirer of Couperin as well.
We'll follow that thread for a bit this Thursday night.
The survey of the symphonies of Jean Sibelius continues with the Third Symphony in C, and we'll hear some other and completely different music from Scandinavia as well.
