Guest performances refer to special appearances by artists or performers who are not part of the main cast or group. These performances can occur in various settings, such as theater productions, concerts, or television shows. Guest performers often bring unique talents or perspectives, enhancing the overall experience for the audience. In many cases, guest performances are used to attract more viewers or fans, as they may feature well-known figures from the entertainment industry. For example, a popular musician might join a band for a special concert, or a celebrity might appear on a TV show to boost ratings and engage a wider audience.
