Look at the birth chart of Neil Diamond and you notice the potential for the artist in his chart. Venus is square Ascendant, the Moon is the oriental planet and Neptune is calling. There is a 105 degree quindecile between Venus and Neptune to complete the picture.
Venus is the planet of talents and Neptune is the planet of arts (fantasy, the amorphous). The Moon is a handy tool for an act or an actor. And a quindecile (range of 15 degree) aspect makes one very focussed, if not obsessed by an idea and in this case it is a strong focus on arts and the life of an artist.
