Simu Liu is serious about music.

After showing off his singing chops in “Barbie” and during the Junos, the Canadian actor surprised concertgoers with a performance at AJ Rafael’s sold-out show in Vancouver.

The surprise appearance has evidently been in the works for some time. Back in April, Rafael announced on Twitter he was planning a tour, asking where he should play, and Liu jumped in to ask, “CAN I COME.”

And it wasn’t just the Kings of Leon cover either. Liu also performed two original songs, his debut single “Don’t” and another mystery song.
