hmm oh man, talk about a 'toughy', im not intimately familar with this but your question has put me out to discover this music too (broaden my horizons. thank you!

)
here's some of what I am initially finding (also is it composers born in Georgia or can it be composers not born in Georgia that composed piano pieces using themes Georgian in origin/nature? what about transplants? i.e. non native born but then move to, live, compose in, georgia etc. too? just thinking about how to filter my research questions as it helps me sift through the data....)
im pasting from a few windows i have open based on initial searches, also soureces included 'non piano non solo' works too but i thought it might be cool to know info too (also for time sake i just included it all vs individually going in line by line across multiple sources to pull them out).

i have scores to some of the above but do not fully know if they are 'postable' i'd feel more comfortable emaling them directly (or where file size is too large give you a secure download link to my google drive so only your email address has access to it then once you confirm you have them i can lock the files again).
do let me know. you can PM me or even just create an email for this only and send me that. if you do , gmail.com email's are easier to use for this.
hope this helps a little. let me know.
