leader Imelda Marcos, was turned into an Off-Broadway musical at The Public Theater in the spring of 2013. Among more recent Nonesuch signings, the most commercially successful has been The Black Keys, the former Akron, Ohio-based duo who parlayed cult status as no-frills blues rockers into an arena-sized following and received multiple Grammy Awards for their 2010 album Brothers and their 2012 release El Camino. Forward-thinking traditional groups Carolina Chocolate Drops and Punch Brothers also joined the label, as well as iconoclastic folk interpreter Sam Amidon. The Chocolate Drops, a group exploring the African-American roots of old-time music, won a Grammy Award for Best Traditional Folk Album for its Nonesuch debut, Genuine Negro Jig. Mandolinist and composer Chris Thile of Punch Brothers was named a 2012 MacArthur Fellow, receiving one of 23 “genius” grant awards to extraordinary practitioners in a variety of creative fields. As a solo artist, he has also joined the classical ranks of the label, releasing the first of three discs of Bach's Sonatas and Partitas, written for the violin but transposed by Thile for mandolin. Nonesuch has been building a catalog of Broadway cast recordings, including several works by multiple Tony and Grammy Award-winning composer/lyricist Stephen Sondheim. The label has released the cast recordings of several Broadway revivals of Sondheim's musicals. Among them are the 1998 production of Gypsy (music by Jule Styne, lyrics by Sondheim); 2002's Into the Woods; 2010's A Little Night Music; and Irish director John Doyle's reimaginings of Sweeney Todd (2006) and Company (2007). The label also released the soundtrack to Tim Burton’s film adaptation of Sweeney Todd, starring Johnny Depp, in 2007. Nonesuch has also released recordings of less well-known Sondheim works like Saturday Night (his first) and The Frogs, as well as first recordings of his new musical Bounce and its later incarnation, Road Show. From the next generation of composers, Adam Guettel has made three recordings for Nonesuch: the cast recording of his first musical, Floyd Collins (1996), the Original Cast Recording of his Tony Award-winning The Light in the Piazza; and his song cycle Myths and Hymns (earlier mounted off Broadway under the title Saturn Returns). Among the champions of Adam Guettel's work is five-time Tony Award-winning singer and actress Audra McDonald, who has showcased his compositions, among the works of a number of other contemporary composers, on her 1998 Nonesuch solo debut album, Way Back to Paradise,
