Jonathan Landrum Jr. LOS ANGELES — The Grammy Awards will adopt an inclusion rider, an important step toward making the premier music awards show more diverse. The Recording Academy announced Wednesday that next year’s 64th annual awards will be produced with a contractual requirement designed to ensure equity and inclusion at all levels of production. Academy President and CEO Harvey Mason Jr. called the concept a “monumental step” for an inclusive music community. The full inclusion rider will be released publicly on Sept. 16. The rider requires the production company staging the Grammys to recruit, audition, interview, and hire onstage and offstage people who have been historically and systematically excluded from the industry.
