Ruby Walker’s blues guitar wailed each night along Beale Street, every chord heavy with heart. One sultry evening, she found an old leather-bound journal left on the stool next to hers at the club. The first page held a faded song lyric: “If you seek soul, follow the river’s curve.” Intrigued, Ruby traced the Mississippi, the city’s soul echoing with her every step. At an old record shop near the river, the owner handed her a vinyl with a secret track. The lyrics whispered: 'Seek the mural where legends rest.' Ruby hurried to the famous wall of Memphis’s musical icons. She pressed her hand to B.B. King’s painted guitar—and a small door popped open, revealing a harmonica and another clue: 'Play at midnight, where souls gather in the park.' At Tom Lee Park, under the moon, Ruby played a soulful tune on the harmonica. The wind carried her melody, and spirits of the city’s past musicians seemed to gather, each adding a note to her song. As dawn broke, Ruby realized the journal’s final secret: Memphis’s soul wasn’t just in the music—it lived in every story, every secret, every song passed down. That night, she wrote her own lyric: “Soul is a circle, a secret you sing, and the city will echo it back to you.” The blues would never sound the same.
