K-pop group CORTIS discussed their new collaboration "Motion" with veteran rapper Juicy J in a backstage interview at Lollapalooza 2026, filmed for Billboard's "All Access" video series. The clip highlights a cross-genre pairing between the boy band and the Southern hip-hop veteran, and touches on the pair's live debut of the track despite weather disruption at the Chicago festival.

Rain caused a delay to CORTIS's Lollapalooza set, though the group say fans stayed enthusiastic throughout. A member of CORTIS described being a long-time fan of Juicy J, citing his influence in introducing them to Southern hip-hop, while Juicy J praised the group's versatility across singing, dancing and rapping, reflecting on his own two-decade career and continued enthusiasm for working with new artists.
