What is the author's style in Angels Fall by Lanford Wilson?

The dramatic structure of Angels Fall is best described as a 'sealed-room' play in which characters who may not know each other or who are very different from each other are forced together due to an unforeseen or unknown circumstance. The accident at the Chin Rock mine results in the characters not being able to go anywhere until notified by authorities. All of the characters are affected in different ways by this news in terms of where they are supposed to be going, yet having their plans on hold allows each of them to take the time to interact with people whom they may not typically meet. Thus, a priest, a professor, a tennis player, an art gallery owner, and a scientist are brought together, each with his or her particular worldview. Although these world views clash throughout the play, there are occasional moments of understanding. The accident literally seals the characters off from the world, except for the radio and phone, thus allowing time to be placed on hold.
