/ˈbæklaɪn//ˈbæklaɪn/The term "backline" has its origins in the music industry, specifically in the context of live performances. In the 1960s, when rock and roll bands began to tour, they needed a system to handle the complex equipment required for their shows. The "backline" referred to the array of amplifiers, speakers, and other audio gear that was situated at the rear of the stage, behind the performers. Over time, the term has expanded to encompass other equipment used by musicians, such as drums, keyboards, and instruments. In modern usage, the term "backline" often refers to the collective technical and logistical support crew responsible for setting up, operating, and maintaining the equipment, as well as providing technical expertise to ensure a smooth and high-quality performance. Despite its evolution, the core concept of "backline" remains centered around the equipment and personnel that support the musicians on stage.
