Anyone interested in Lithuanian piano music owes it to him/herself to look into the works of Vytautas Bacevicius, a twentieth-century pianist/composer who I would rank alongside other modern piano greats like Nikos Skalkottas and Samuil Feinberg. His style vacillates between neoclassicism and Scriabinesque mysticism, but those terms are meaningless and people should just check the music out. His sibling was the great Polish female composer Grazyna Bacewicz (who also wrote some marvelous piano music in her time). Just recently, the Toccata label has been releasing some really awesome stuff by him for the first time, such as:
If any players are interested in adding some rare and exciting music to their repertoire, a few years ago I located some extremely rare early works from this composer, including a set of preludes and some Lithuanian dances (the latter still needs to be scanned). I'd be willing to pass them on to anybody who's curious.
