Co-headliners are two or more performers or acts that share the spotlight during a concert, festival, or event. Each co-headliner typically has equal billing and is given a similar amount of stage time, allowing them to showcase their talents to the audience. This arrangement can attract a larger crowd, as fans of each act are likely to attend. In the music industry, co-headlining tours are common, where artists like Taylor Swift and Ed Sheeran might team up to perform together. This collaboration can create a unique experience for fans, as they get to enjoy multiple popular acts in one show.
