Piano transcriptions of great music works created by Roman Maciejewski, like his many other compositions, they were ‘taken out of the drawer’ by his brother Wojciech only in the late 1980s. It is a varied collection including four-handed or two-piano compositions. These stylistically and formally diversified works are masterpieces of the musical repertoire of all ages. When reaching for this repertoire today one should be aware of the specific character of such works and their performance. On the one hand, it is a form of popular music, but on the other they are individual interpretations of great musical masterpieces.
