The artist formerly and possibly again known as Kanye West reveled in support from one of his musical idols, Lauryn Hill, as he staged a sold-out Southern California concert meant to mark a comeback from years of controversy. Eleven months after releasing a song titled “Heil Hitler” and just over two months after publishing an apology letter for his antisemitism, Ye let his two decades of hits — and 70,000 screaming fans — speak the loudest on Friday night at SoFi Stadium. Hill joined Ye on a stage for the first time ever for an energetic rendition of his 2004 hit “All Falls Down,” which originally sampled her voice.
