Miniature as it is used here does not so much refer to a piece that is brief as it does to one that is fashioned in great detail, like the elaborately decorated initials of medieval illuminated manuscripts or some of the miniatures from India. Estrose is an untranslatable word with various shades of meaning, having to do with imagination, creative intuition, inspiration and genius, but also extravagance and eccentricity. Suffice it to say that Antonio Vivaldi chose this same word for his LEstro Armonico (Marco Stroppa). Pianist Erik Bertsch presents this album of fascinating piano music, which took almost 20 years for Stroppa to write.
