Bassist extraordinaire Thundercat welcomed special guest Ariana Grande for his recent set at The Adult Swim Festival, jamming to his fan favorite “Them Changes.”

Thundercat was also backed by JD Beck, and DOMi for the tune, but it was the interplay between Thundercat and Grande (both of whom were close friends and collaborators with the late Mac Miller) that made the performance particularly striking.

“Mac changed my whole life,” Thundercat told Relix in early 2020. “You only get a few friends who you can call your best. He was somebody I’d trust my daughter with, someone who’d go to church with me.”
