Now well over 20-years old, this Naxos CD is certainly worth hearing if you don't have the Borodin symphonies in your collection, particularly as it can be bought for pennies. Stephen Gunzenhauser conducts the then CSR Symphony Orchestra in a blazing perormance of Symphony 1, 2 is pretty good, and the "rump" of the unfinished 3 completes the CD.
A full-time chemist, Borodin is one of the great "what-ifs" in Russian music; even his acknowledged masterpiece, the opera Prince Igor, had to be completed after his early death by Rimsky-Korsakov and Glazunov. Aside from these symphonies and Prince Igor, Borodin left us some lovely chamber music (well worth investigating; try Borodin: String Quartets; String Sextet
) a handful of songs, and a few other bit and pieces.
There are, I think, other recordings of these symphonies that are probably a little more polished. My top recommendation is the cycle set down on RCA by Tjeknavorian and the National Philharmonic. This was long unavailable, but can now be found as a good value CD - Borodin - Symphonies Nos 1 - 3
, but don't dismiss this Naxos CD!
