Though Twitch doesn’t release traffic or engagement numbers of specific users, Mike Olson, the company’s head of music, said Diplo is “performing really well.” He cited Diplo’s consistency and ability to connect with the audience — he repeats things like, “heck yeah, we’re dancing” into the microphone, which results in a spike of comments and emoji, or “emos” as they’re called on Twitch. “He’s doing a lot of things right,” Mr. Olson said.

There have been missteps. Diplo was meant to spend the second weekend of March in New York, shooting a music video and preparing for the South by Southwest and Ultra Music festivals. When all of that got canceled, he went to his local Target and bought a fog machine. In his living room, he set up a green screen. Because of his Sirius XM satellite radio channel, he already had the equipment needed to broadcast high-quality sound from home.

He called Parris Goebel, a choreographer and friend. “I was like, ‘I don’t want to be at home just reading the news all day because that’s probably not good for my mental health,’” Diplo said.

Ms. Goebel sent him a troupe of “the best dancers in L.A.,” he said, and they twerked around him, wearing face masks, while he played dance music. “We got a lot of flak for that because that was the first week of social distancing, and we were definitely not doing it right.”

Now, the dancers have their own green screen and camera setups at home, so he can showcase them safely. “We bought so much technology to make it so that everybody who dances for me can dance remotely,” he said.

‘Starting to Get Fat’

He still has occasional IRL collaborators, like Mr. Francis, who is signed to Diplo’s record label, Mad Decent, and comes over every Saturday for Coronight Fever. “The only reason we’re doing that is because we were the last people we saw before we started quarantining,” said Mr. Francis, who is 32. “We know exactly who we’re seeing, which is just each other, and the people that live in Wes’s house. I go and eat Wes’s food. It works out for me perfectly.”
