$114 MILLION GROSS FOR CHESNEY: Diamond, who has booked Ed Sheeran in North America since the singer's club days seven years ago, helped the "Shape of You" singer-songwriter fill stadiums and take the No. 1 spot on Billboard's year-end Top 25 Tours ranking. Sheeran's current global gross is $433.5 million. (CAA reps him outside of North America.) In November, Kenny Chesney, who ranked No. 9 with a $114 million gross, joined the agency's roster. Galle booked Shawn Mendes’ first stadium sellout – this coming September in the singer’s native Toronto. Galle lured Missy Elliot to Paradigm, while Galle and Martin brought Janet Jackson to Paradigm for global representation. Martin balanced work as a partner in Riot Fest with finding producing partners for Imagine Dragons frontman Dan Reynolds’ Believer documentary while guiding the careers of Rise Against and K.Flay. Levine works with Kacey Musgraves, Sturgill Simpson and Margo Price -- artists, he says, who "won't bend to the constraints of the music business."
