an occasion when a person or group of people go onto the stage where a singer or a band is performing

The gig finished with a mass stage invasion. 这场演出以大群人冲击舞台而结束。

Perhaps the most famous commotion was Jarvis Cocker's stage invasion during a performance by Michael Jackson in 1996. 最著名的一次骚动也许是贾维斯·科克尔在1996年迈克尔·杰克逊的一场演出中入侵舞台的事件。
