Jimi Hendrix’s guitar, Whitney Houston’s outfits, Ella Fitzgerald’s coat, vintage photos, and 1,500 other items are on view at the new National Museum of African American Music, which opened on Martin Luther King Jr Day in Nashville. It covers 400 years of black music, from gospel to jazz and R&B, presenting some of the most famous musicians like Elvis Presley, Jay-Z, and The Fugees, to some lesser-known like Ma Rainey and Sister Rosetta Tharpe. Guardian visited it.
