Here's the cadenza to the third movement of K450. To be honest,
although it's interesting to hear non-Mozart cadenzas, the best
ones are invariably Mozart's originals, in my very biased opinion!

Please note that the cadenza to the first movement of K450 (Op87 No18)
is already available on IMSLP.

The remainder (K238 and K246) will follow later on today.

Here are the remainder. I wonder if we're still missing any of Op87?

now we have all of them, except no.22 which is absent in this edition

Indeed, Op87 No41 appears to be the rather elusive cadenza for the
first movement of K482.

This file is really scraping the barrel - it's the last page with 'preview'
printed across it.

sounds interesting

Lengnick edition

Methinks I'll buy a copy!

Re K482, Benjamin Britten and Wanda Landowska also wrote cadenzas
for this concerto. Here's Richter playing the whole work with Britten's
very unMozartian cadenzas. Whether it's good practice to mix things
up stylistically, I'm not too sure.

now are in stok Busoni's cadenzas by Braitkopf in three volumes, Landowska's cadenzas for 7 concerto, Lily Kraus' whole concertos set, Geza Anda's, Robert Casadesus, Wilhelm Kempff, Edwin Fischer, Badura-Skoda's brilliant Cadenzas and leadings issued by Barenreiter, Salvatore Sciarrino's short cadenzas (Pollini plays 21th). Britten, Gulda, Brendel, several cadenzas of Andras Shiff can find on Henle site, preview is free, I made screens.

Also I have 350 recordings of cadenzas of great pianists, if you are interested I can send you them 1.14 gb

It would be fun to list every pianist or composer who has published
cadenzas for WAM piano concertos. Six composers spring to mind,
apart from those already mentioned:- Alkan, Brahms, Hummel,
Saint-Saëns, Clara Schumann and Smetana. There must be quite
a few other composers as well, and numerous more pianists.

generally I prefer cadenzas by XX century pianists, especially Mozart experts like Perahia, Brendel, Badura Skoda, Flothuis etc. stylistically closer to Mozart idea, Alkan and Smetana are terrible, even Brahms and Saint-saens. after Hummel it's too har d to find good cadenza

there are several brilliant cadenzas, never published, maybe even never recorded and only been played by heart, for example Clara Haskil's, two years ago I wrote to Artur Schnabel Foundation and soon they issued his Mozart cadenzas, but I do not like scoring

I tend to agree with you about preferring the XXth century pianists' cadenzas,
who probably didn't feel the need to impose their own personalities as much.

Here are a couple of modern cadenzas for K466 which are worth a listen,
by the late great Pierre Sancan and the very youthful Theodore Servin.

As with variations on themes, certain concertos seem to attract far more
cadenzas than others, K466 being a good example.

The even more youthful Alma Deutscher did a good job with K246.
