Four artworks are better than one; ‘specially if each one represents a different oeuvre.
Any four artists working individually, but exhibiting together can present a maximum viewing experience. Four seems to be about right for public viewing of artwork. More artists can be confusing, watering down the impression that a viewer takes away. Fewer artists tend to become individualised, defeating the purpose of viewing together.
Take4Artists will be testing this concept at their initial exhibition in a few months time.
