At last Hiller's Grand Duo Op135 for 2 pianos has been recorded (with works already available elsewhere by Moscheles, Chopin etc) However, my disappointment here, which I suspect may be shared by others, is the fact that again we have to endure the dreaded "historic instruments"! But perhaps the sound may just be acceptable enough to give us an idea of the work, or better still, encourage a recording on a couple of modern pianos!!https://www.jpc.de/jpcng/classic/detail/-/art/grand-duo/hnum/6808863 (https://www.jpc.de/jpcng/classic/detail/-/art/grand-duo/hnum/6808863)
