I guess I'm still in the mood for Russian music. Two recordings, the first by Alexander Borodin (1833-1887) and the second by Dmitri Kabalevsky (1904-1987).
First piece: Prince Igor: Polovtsian March
Second piece: Colas Breugnon, Op.24 -- Overture
What's so interesting about listening to these composers one after the other is getting a sense of the transition in music from late Romantic to modern.
