The Knowles sisters are among the few superstar musicians who belong as much to Houston as to the world, and since Beyoncé's Lemonade came out just before our timeline, Solange doesn't even need to flex. Her first No. 1 album, A Seat at the Table, is as much an artistic statement as a public one, speaking to issues of race, gender, injustice, self-care and self-reliance, in language that is both poetic and plainspoken. It's a self-assured work, recalling the confidence and content of Nina Simone, a soundtrack to the pain and promise of America, with a loose-fit, unstuck-in-time production style filled with '60s spoken-work interludes, '70s funk zing and '90s R&B zang.
