The brief concert, at the Golden 1 Center in Sacramento, came two nights after Mr. West shocked his audience by announcing at a show in San Jose, Calif., that he had not voted, but would have cast a ballot for Mr. Trump if he had. Though the rapper affirmed his belief in the importance of issues like Black Lives Matter and women’s rights, he praised Mr. Trump’s “method of communication” as “very futuristic.”

On Saturday night, in a trademark polemic the likes of which had been mostly absent from his current Saint Pablo tour, Mr. West doubled down on his embrace of Trump-like political incorrectness and opined on the state of the media. “Yeah, I’m taking his lead,” Mr. West said of the president-elect.

“A lot of people here tonight felt like they lost,” the rapper began. “You know why? Because y’all been lied to. Google lied to you. Facebook lied to you. Radio lied to you.”

Turning his focus on the music industry, Mr. West questioned gatekeepers for promoting songs by Drake but not Frank Ocean, and wondered once again why he is often overlooked at awards shows. Referring to this year’s MTV Video Music Awards, Mr. West pulled back the curtain on what he said was the political behind-the-scenes dealings that go into booking celebrities for such events.
