Both Lynyrd Skynyrd and Elvis Presley have been noted to draw some inspiration from the Civil War's musical legacy, though not necessarily directly or extensively in their primary body of work.
Lynyrd Skynyrd: This Southern rock band, known for songs like "Sweet Home Alabama," has a musical style that reflects a Southern cultural heritage which includes influences from various historical epochs, including the Civil War era. The spirit of Southern pride, which can indirectly harken back to Civil War narratives, is sometimes reflected in their music. The band's music celebrates Southern identity and occasionally touches on themes tied to historical evocations (BBC).
Elvis Presley: While not directly inspired by the Civil War, Elvis's music was part of a wider American musical tradition that includes elements dating back to that era. Presley's style was heavily influenced by gospel and blues, both of which have roots in the tumultuous history of the American South, including the Civil War and its aftermath. It is noted how historical American music, stemming from the Civil War period, has evolved and influenced various artists across centuries, including Presley (BBC).
