The Milk Carton Kids is an indie folk duo from Eagle Rock, California, consisting of singers and guitarists Kenneth Pattengale and Joey Ryan, who formed the group in early 2011. NPR has described their approach to music as "gorgeous contemporary folk" and “Gillian Welch & David Rawlings-meets-Simon & Garfunkel with a splash of the Everly Brothers”, which fairly represents the band’s music while also appealing to the intended audience. The band has recorded and released three albums, Retrospect, Prologue, and The Ash & Clay. The foreword to "Prologue" was written by singer-songwriter and producer Joe Henry. The band is noted for releasing their albums for free and for playing their vintage guitars with Ryan on a 1951 Gibson J45 and Pattengale on a 1954 Martin 0-15. The band's general manager is Nick Bobetsky.
