Mumford & Sons are a British folk-rock band formed in 2007, consisting of Marcus Mumford (lead vocals, guitar, drums), Ben Lovett (keyboards, piano), and Ted Dwane (bass guitar). Known for their powerful harmonies, introspective lyrics, and energetic live performances, Mumford & Sons rose to fame with their debut album, "Sigh No More," in 2009. This album, featuring hit singles like "Little Lion Man" and "The Cave," helped bring a revival of folk and Americana influences into mainstream music. Their sound is characterized by a mix of folk instrumentation, such as the banjo and acoustic guitar, combined with elements of rock and alternative.

Their 2012 follow-up album, "Babel," continued to build on their success, winning the Grammy Award for Album of the Year and featuring popular songs like "I Will Wait." In 2015, the band took a creative turn with "Wilder Mind," which saw them embracing a more electric and rock-oriented sound, trading the banjo for electric guitars and synthesizers. Known for their evolving musical style, Mumford & Sons have continued to experiment and push genre boundaries while maintaining their lyrical focus on themes of love, faith, and personal reflection. Their journey from a folk revival band to a versatile rock act has earned them a loyal fan base and solidified their place in the contemporary music scene.
