I like arriving at a concert, or movie ahead of time.

This expression is used to say that the person likes arriving early to these events, usually so that they can become comfortable and relaxed before the event begins.

看電影、聽音樂會，我喜歡提早到場。

Ahead of time（提前、提早）作副詞片語，修飾句中的動詞。提早到達電影院、或音樂會場，可免除遲到所帶來的損失與尷尬。
