The Fillmore, 8656 Colesville Road, Silver Spring; Thu., 7:30 p.m., $29.50.

‘I Like Me Better’ by Lauv
During rehearsals for his tour, Sartorius and his band were “jamming out to [‘I Like Me Better’] and we were like, ‘Let’s put that into the set.’ ” Now he’s covering the catchy 2017 pop song by Lauv, whom he recently met at the Jingle Ball in New York.

‘But a Dream’ by G-Eazy
“It just talks about [how] life is kind of like a dream and you gotta just live it,” Sartorius says of the 2017 rap song. “Too often I get caught in my own headspace and [get] panicked. … Once I let go of my worries and live in the moment, it’s such a good feeling.”

‘Waving Through a Window’ by Ben Platt
This showstopper from “Dear Evan Hansen” — “my favorite musical of all time” — speaks to Sartorius, who’s seen the Tony-winning show twice on Broadway. “You feel like you’re an outsider and you don’t belong. … I was so inspired once I saw that show.”
