Finally, the quality of entertainment is key to the creation of a public sphere where discussions about the concert's cause can occur. The better the entertainment, the more people watch the concert, and thus the more people become aware of the cause. Furthermore, the music played in the concerts can lead spectators to interconnect and become more likely to act towards the cause. According to a theory, by Jane Bennett, when people sing in the presence of other people, and that happens in benefit concerts, they become connected to each other and are more likely to work together towards a goal.
