2000s: Raising Sand, Rounder Books, Mary Chapin Carpenter, Steve Martin
While polka was a mainstay of Rounder's catalog, in 2001 the company moved the musical style to the mainstream with the release of Jimmy Sturr's Gone Polka album. "Unabashed polka fan," Willie Nelson, whose first bands played polka, often recorded on Sturr's albums, and four songs on Gone Polka featured Nelson's vocals, illustrating "the happy cross-cultural union between the Lone Star State and Eastern Europe."[45]
In 2002, Rounder signed a deal with Provident Music Distribution to sell Rounder products to Christian retailers, and began marketing the recordings of jazz saxophonist Branford Marsalis's Marsalis Music label.[46]
Rounder Books was created in Spring 2004. The division's first releases were Nowlin's baseball biography Mr. Red Sox: The Johnny Pesky Story, and a book of collected fan essays, edited by Nowlin and Cecelia Tan. Nowlin, along with other co-writers, released another three Red Sox-themed books over the next six years.[47] Other titles from Rounder Books included a children's book by Raffi, Everybody Grows, and the company's bestseller, Rush drummer/lyricist Neil Peart's Roadshow: Landscape with Drums—A Concert Tour by Motorcycle.[48]
In 1986, although pursued by Rounder, Mary Chapin Carpenter chose instead to sign with Columbia Records. Twenty years later, in 2006, she signed with Rounder.[49][50] Moving beyond the country music she was associated with, on Rounder she released what many fans and critics regarded as the best albums of her career.[51][52]
Echoing the early achievements of Hazel Dickens and Alison Krauss, in the male-dominated field of bluegrass music, in 2007 Rounder released Crowd Favorites, a compilation of six albums by Claire Lynch. The album earned multiple International Bluegrass Music Association (IBMA) awards and Lynch was inducted into the Alabama Bluegrass Hall of Fame.[53] In 2005, Lynn Morris, Alecia Nugent and Rhonda Vincent were honored by the Society for the Preservation of Bluegrass Music of America.[54]
The Robert Plant/Alison Krauss album, Raising Sand, in 2007, was one of Rounder's biggest hits both commercially and critically. It won five Grammys, including Album of the Year, Best Contemporary Folk/Americana Album, Record of the Year (for "Please Read the Letter"), Best Pop Collaboration with Vocals for "Rich Woman," and Best Country Collaboration with Vocals for "Killing the Blues". Krauss was the sixth female artist to win five Grammys in a single night. Raising Sand was certified platinum in March 2008.[55]
In 2009, Rounder reissued a series of 1920s and 1930s Carter Family recordings.[56][57] The same year, the label launched what would become a 100-disc reissue series compiled by musicologist Alan Lomax whose archival project began in 1938 with the taping of Jelly Roll Morton, and ultimately included Lead Belly, Muddy Waters, Woody Guthrie, and many others.[58] Steve Martin also released the first of his Rounder albums, The Crow: New Songs for the Five-String Banjo in 2009.[59]
Releasing about 100 albums per year by the end of the decade, Rounder's catalog had grown to include Del McCoury, David Grisman, the Whitstein Brothers, Madeleine Peyroux, and James King, as well as supergroups Dreadful Snakes (Jerry Douglas, Pat Enright, Bela Fleck, Mark Hembree, Blaine Sprouse, and Roland White) and Longview (Dudley Connell, James King, Don Rigsby, Joe Mullins, Glen Duncan, and Marshall Wilborn), and the compilation Oh Sister.[60] Artists including Robert Plant, Dolores O'Riordan, Ann Wilson, Fleck, Minnie Driver, Rush, Cowboy Junkies, Griffith, Laura Nyro, Fairport Convention, Linda Thompson, Boz Scaggs, Nelson, Skaggs, and Joe Diffie among others, recorded for Rounder during the 2000s.[13]
