Two black Antiphons of 2001 by Milan Grygar, who has been dealing with the relationship of image, sound and space in his art for five decades, build on similarly conceived black paintings from the 1980s. They reflect Grygar’s experience with the combination of visual and acoustic aspects, first employed in his acoustic drawings and scores from the mid-1960s. Both paintings are a follow up to this early work, which is represented in the collections of Prague City Gallery by the substantial, large-scale Big Drawing with a Stick of 1967, and a series of acoustic drawings from the 1970s.
