Virtuoso jazz in classical form: Nikolai Kapustin (b. 1937) is an excellent jazz pianist, arranger and composer. His piano sonatas are now published by Schott Music for the first time. Suitable for pianists looking for technically demanding pieces between modern and jazz music which sound like highly skilled, yet notated improvisation.
Difficulty level, roughly compared to ABRSM exam grades. 0 is beginner, 9 is advanced (beyond grade 8).
