Like everyone in the United States, John Legend has spent much of the past year in lockdown. He has been recording new music (via Zoom), performing on Instagram, and promoting his upcoming album. Though many artists have delayed releasing records until they can schedule concert dates—increasingly the most reliable revenue in the music industry—Legend didn’t want to hold back. The new album, “Bigger Love,” was written before the pandemic and the current groundswell of protest for racial justice, but his message about resilience and faith resonates. All art, Legend tells David Remnick, “is there to help us imagine a different future.”
