Final answer:
Artists can communicate social issues via political art, street art, activist art, and contemporary art forms like installation and digital art, which serve as platforms for social critique and engaging the public in discourse around needed social change.
Step-by-step explanation:
An artist's strong ideas about social issues can be effectively communicated through various art forms. Political art became a prominent means of protest for marginalized communities in the 90s, including racial minorities, the LGBT community, and women. These groups engaged in the creation of art that challenged existing social structures and provided a platform for their voices to be heard.
Street art, such as graffiti, has become a powerful tool for communicating social and political messages. Artists like Banksy have utilized street art to comment on and protest against issues such as commercialism and political corruption. This form of expression has been controversial, debated as either a criminal act or a legitimate artistic medium.
The strategies of activist art have also included collaboration, dialogue, and respecting the audience's engagement. Feminist art, for example, used these methods to address issues of empowerment and community identity. Activist art functions as a means of personal revelation that can become a political instrument, influencing public perception and spurring social change.
Contemporary artists have also adopted the concerns of the conceptual art movement, utilizing ideas and information as their medium. This is evident in the use of installation art, performance art, net art, and digital art as platforms for social critique and political engagement.
Community-driven art projects, such as the positive signs project, utilise art for social action and to spread positive messages, challenging negative public signages.
Finally, cultural expressions through art, music, and sports articulate experiences of resistance and rebellion, playing key roles in contemporary culture's discourse on the need for change.
