Poetry slams are unique artistic events where two or more poet “battle” in a competitive environment. Sometimes the battle is more for fun and in other cases the participants are competing for awards, prizes, and recognition such as this example: https://www.australianpoetryslam.com/champions
Not all artists / poets though view poetry slams as having as much artistic merit as traditional poetry. In some cases these views may be based on more traditional / conservative views of poetry. Others may view the competitive nature of poetry slams as having a negative effect on the art.
