The veteran jazz pianist Robert Glasper has always been a prolific collaborator, traveling outside of jazz into the worlds of rap and R&B. Glasper has worked with artists like Kendrick Lamar, Mac Miller, and Q-Tip. In recent years, he’s taken part in supergroups like August Greene, R+R=Now, and Dinner Party. In 2019, Glasper released his Fuck Yo Feelings mixtape, which included tracks with artists like Yasiin Bey, Herbie Hancock, and Denzel Curry. Last night, Glasper was the musical guest on Jimmy Fallon’s The Tonight Show, and his performance featured a whole crew of special guests.
