I like Nazareth a lot as well, much better than Joplin (which he resembles on a superficial level). But while Joplin in much of a sameness, Nazareth can be incredibly varied not restricting himself to only one rhythm pattern. The 2 CDs by Artur Moreira Lima are the essential ones (Moreira Lima is a classical pianist, playing Nazareth as classical music – Nazareth would undoubtedly be very happy, since he always regarded himself as a classical composer and tried to avoid the label of popular music). This site has a brief biography and several CDs:

https://www.ln.com.br/Have you ever heard of Chiquinha Gonzaga (Nazareth’s comtemporary)? She also wrote many songs (not pieces!) on a similar, albeit more lyrical style. The allbrazilian site I mentioned above also has information on her.
And here is another interesting Brazilian composer of the same style (“Choro”): Zequinha de Abreu, whose most popular composition Tico-Tico no Fubá (“Little bird on the cornflour”) merited a special piano arrangement from no less a luminaire than Marc Andre Hamelin. You can listen to the midi and print the score from:
