I bought two cpo CDs several years ago with her three symphonies and two concert overtures, and have recently come back to them. I always really liked them, but now that I've been getting more into Romantic-era music, this time I'm absolutely blown away... specifically by the Symphony #1 in C minor. Now that I've been listening to this work again - repeatedly! - it strikes me as a truly great symphony. Taken as a set, her complete orchestral works are just staggering to me; maybe I'm alone in this, but I honestly can't get enough of all of these works lately. Especially the first movements of all three are just incredible! The scherzo of the Symphony #3 also seems like a Raff-like work of genius.
Maybe they're cherry picking what "they" consider Farrenc's best works, but I got some of her chamber music and there are a Piano Sextet and Piano Trio that are just magnificent. I understand that the Piano Sextet is often considered her finest work. Unfortunately, there really isn't much more to record, as she didn't write all that much. What I wouldn't give for a Symphony #4!
As far as I'm concerned, based on the few works I have, Farrenc has one of the highest batting averages of all composers.
By the way, note the spelling of her name: Farrenc.
