How did Lynyrd Skynyrd cement their Southern sound? By blending bluesy gusts of guitar from The Rolling Stones (“Wild Horses”) with the freewheeling jams of The Allman Brothers (“Jessica”), and adding Clapton's straight-ahead grooves on a “Bottle of Red Wine” to the airy heaviness of Led Zeppelin (“Stairway to Heaven”)—creating an unmistakably original vibe based around laidback-yet-tight guitar, seasoned singing and mellow beats.
