Bon Iver is an American indie folk band founded in 2006 by singer-songwriter Justin Vernon. The name "Bon Iver" is derived from the French phrase bon hiver, meaning "good winter." The band's debut album, For Emma, Forever Ago (2007), was recorded in a secluded cabin in Wisconsin and gained critical acclaim for its raw emotion and hauntingly beautiful melodies. This breakthrough led to widespread recognition, setting the stage for subsequent albums like Bon Iver, Bon Iver (2011), which won Grammy Awards for Best Alternative Music Album and Best New Artist. Over time, the band has evolved beyond its folk roots, incorporating elements of electronic, jazz, and experimental music into its sound.

Bon Iver's later works, including 22, A Million (2016) and i,i (2019), further pushed musical boundaries with intricate production, cryptic lyrics, and innovative soundscapes. The band is known for its ethereal harmonies, Vernon's distinctive falsetto, and the ability to craft deeply introspective songs that resonate with listeners. Bon Iver has collaborated with artists like Kanye West, Taylor Swift, and James Blake, influencing a generation of musicians. Their live performances blend intimate acoustic moments with grand, atmospheric arrangements, making them one of the most unique and celebrated acts in modern music.
