A "Curtain Raiser" is an event or performance that serves as a preview or introduction to a larger show or production. It often takes place before the main event, allowing the audience to get a taste of what is to come. This format is commonly used in theater, music, and other performing arts to build excitement and set the tone. In addition to live performances, a curtain raiser can also refer to promotional activities or presentations that highlight upcoming projects, such as film releases or art exhibitions. These events aim to engage the audience and generate interest, making them an essential part of the entertainment industry.
