JiLL-Decoy association, whose originality shines through jazz-, pop-, and rock-based songs and love-filled vocals that color them, is returning to Billboard Live for the first time in about a year and a half. Formed in 2002 and making their major debut in 2006. In 2013, their album 『ジルデコ5』 won the Excellent Album Award at the 55th Japan Record Awards, and 2021—marking their 15th anniversary—saw the release of the cover album 『App standard』. They continually release works with a challenging stance, constantly updating their career. On the day of the show, it will be the release date of the new album 『ジルデコ10～double～』, and a live performance where you can experience JiLL-Decoy's latest evolution is a must-see. Don’t miss this long-awaited stage, their first since last year’s 20th-anniversary commemorative concert.
