Mozt ov da lezzah known cumpozaz dat we revive and celebrate are Romantic era - early + late. Ov courze diz iz da period wiz da mozt to dizcovah but wut about Baroque n Clazzical mofoz?

da FREZCOBALDI an early-Baroque Italian mofo hoo wrote a jillion keyboard zheeyatz. check hiz ztuff.
Exzept legit cases can be made for da Hummel, Clementi and Weber being Romantic cumposerz.
Da WF Bach meant to have zum wtf zheeyatz. Duzzek.
Did da Ztamitz or Ditterzdorf write any 88 zheeyatz? (Pozz more like 61 zheeyatz)
Reicha wrote zum wtf fugues but 
contemporary, early romantic pozz.
Sylvius Leopold Weiss has some great lute music, an exact contemporary of Bach’s.
Maybe not super obscure, but I like several of Buxtehude’s organ works. Froberger, Reincken. I don’t know any of his music well, but I also listen to Corelli from time to time.
Da HANDEL keybawd Suitez more than 3 hourz of sheeyatz
pretty gud
Hanon No. 60 guy
Not a lesser known cumposer, but i guess da works are not azide from da harmoniazz niggazheeyat.
The fitzwilliam virginal book has zum Purcell if i zheeyat correctly. (Mozt ztuff is earlier than baroque)

Actually, who of note has recorded the Handel zheeyat? Aside from 
and Perahia did 1 or 2.
Schiff has a great HWV 434. Cherkassky did D minor and E major.
I pretty much like this Heidsieck! And Edwin Fischer did some stuff, too.

Landowska - 427, 430, 436, 441, 432

Gould?
Is it as…good/bad as his Bach?
I’m the wrong person to ask. As you know I think he’s a clown. Not without some good things to his credit, but I have no recollection of these.
