Each performance was relevant to audiences at the time of their premiere because they explored contemporary social issues such as racism (Porgy & Bess), gang violence (West Side Story) and immigration (Hamilton). The works were not only entertaining but allowed people to reflect upon current affairs by exploring them through fictional narratives. Porgy & Bess served as a powerful vehicle for African American expression during the Jim Crow era whereas West Side Story focused on themes such as class struggle & cultural tension between Puerto Ricans & white Americans living in New York City during this time period . Finally Hamilton focuses on our nation’s founding fathers from a diverse range of backgrounds which brings attention to our ever changing landscape today where immigrants make up a large percentage of our country’s population .

Yes I see different values in musical arts after learning more about 20th century music operettas/ballets/musicals due largely in part because these works have opened up conversations about difficult topics that affect us all by allowing us to explore them through empathy filled storytelling techniques instead solely relying on facts or data alone which can often be interpreted differently depending on one’s own personal biases or beliefs . For example while Porgy & Bess may seem like just another lighthearted musical at first glance , it really serves as an important reminder that African Americans deserve respect dignity even when faced with racial discrimination throughout history .

Lastly Hamilton continues this trend by providing perspectives regarding diversity inclusion within our nation’s government structure emphasizing how much there is still left undone if we truly want create equal opportunity for everyone regardless one’s background or circumstances.

These works have also served as a form of artistic expression for their time period allowing people to express themselves in new ways that weren’t available before while simultaneously providing an avenue for audiences to explore varied perspectives on the topics at hand . It’s clear that these performances are still relevant today given their lasting impact even after many decades since they’ve been released which speaks volumes regarding how powerful music can be when used correctly.
