Revered as one of the most powerful and difficult etudes of the romantic repertoire, Scriabin's in D-sharp minor is impressively cohesive, with every phrase leading seamlessly over to the next over vast arpeggios, bass pedal points and poignant harmonic moves. Analysis with pianist Henrik Kilhamn.
(Apologies for the audio quality - somehow my external audio setup didn't record the analysis part so I had to use audio from the keyboard camera which isn't as good and harder to mix with its autolevels.)
