Seconded, or thirded. Another recent Veronika-inspired purchase which has had my hair standing on end many times in recent months including this very moment in fact. (Since I am wearing headphones this can have disastrous effects; must remember to comb hair before going out to tame inverse orthogonal Mohican).   

Similarly (including VL-recommended), this 3CD set from the same stable of the complete percussion works, Steve Schick etc. Wonderful stuff which I am in the process of exploring.

Can't find one of booklet spread, with the fires, so the front will have to do.

I like this recording very much. It is done on an organ (small one) and cello sounds very sweet. It is violoncello piccolo. I never even heard that there is an instrument like that.
I used to listen a lot to this recording.
There are many problems with playing these sonatas. If it is played with the harpsicholrd than the balance is not good. If it is played with the piano, then it is not authentic.

This CD is tastefully done.

Well, since I can't find the Glenn Gould/Stokowski/Beethoven cover I want, here's:

Thank you so much for posting this, autoharp! Now I finally know what the name of this composer is! I heard his music years ago on Belgian radio and I've always remembered that British composer who composed a huge amount of piano sonatas. I only forgot his name. Now I know it. Thank you!
