For his 10th solo studio album, Lullaby and…The Ceaseless Roar, rock legend Robert Plant left behind his country phase and began arranging experimental folk tunes with gritty rock and folk influences.

Plant’s backing band, The Sensational Space Shifters, have been touring with the famed singer since 2012, but Ceaseless Roar marks the first studio album featuring both. Consisting of six musicians who specialize in funky world-music grooves, the instruments used vary from North African bendirs to banjos.

Kicking off the 11-song album is Plant’s arrangement of the old bluegrass song, “Little Maggie,” featuring bewitchingly smooth vocals and a drum beat reminiscent of the old Led Zeppelin days. Going back to blues roots, the track “Poor Howard” comes from the renowned American bluesman Lead Belly. With a music video to go along with it, the album’s most well known song, “Rainbow,” delivers a simplistic yet catchy rhythm.

With ethereal vocals and experimental beats, Lullaby and…The Ceaseless Roar is exemplary of Plant’s musical direction after Led Zeppelin.
