Had a listen to your recordings of these Quatre Preludes which I haven't heard before. Don't have a score but listening back the first is to my ears turbulent (suppose it should be marked "con moto")
but I think you play at speed without any flubs, which is to your credit. I'm going to disagree with Stu about no. 2. I liked it. The passing tones are a nice device and Liadov's exploits the bass register. The agitato comes across from the beginning of this short piece. It brings to mind a bunch of sailor's getting drunk at midnight on an old ship that's rocking back and forth due to a maritime storm.
The third piece does bring to mind Chopin, like a prelude or smth.
The fourth piece uses one line which is nice and uncommon for most "serious" pieces." The trills are crisp and legato. One thing is at 1:17 (where the arp. bass comes in) I would have liked you to linger on the opening note (or just use rubato till the end) of this dream-like section a little longer, but I realize it probably wasn't in the score. Beyond that, I really enjoyed this set.
