funk, hiphop, and jazz influences. While primarily an acoustic guitarist she has used a variety of instruments and styles: brass instrumentation was prevalent in 1998's Little Plastic Castle; a simple walking bass in her 1997 cover of Hal David and Burt Bacharach's "Wishin' and Hopin' "; strings on the 1997 live album Living in Clip and 2004's Knuckle Down; and electronics and synthesizers in 1999's To the Teeth and 2006's Reprieve. DiFranco has stated that "folk music is not an acoustic guitar – that's not where the heart of it is. I use the word 'folk' in reference to punk music and rap music. It's an attitude, it's an awareness of one's heritage, and it's a community. It's subcorporate music that gives voice to different communities and their struggle against authority." Musical collaborations, cover versions, and samples DiFranco has collaborated with a wide range of artists. In 1997, she appeared on Canadian songwriter Bruce Cockburn's Charity of Night album. In 1998, she produced fellow folksinger Dan Bern's album Fifty Eggs. She developed a deep association with folksinger and social activist Utah Phillips throughout the mid-1990s, sharing her stage and her audience with the older musician until his death in 2008 and resulting in two collaborative albums: The Past Didn't Go Anywhere (1996) and Fellow Workers (1999, with liner notes by Howard Zinn). The Past is built around Phillips's storytelling, an important part of his art that had not previously been documented on recordings; on the album, DiFranco provides musical settings for his speaking voice. The followup, Fellow Workers, was recorded live in Daniel Lanois's Kingsway Studio in New Orleans and features Phillips fronting DiFranco's touring band for a collection of songs and stories. Prince recorded two songs with DiFranco in 1999, "Providence" on her To the Teeth album, and "Eye Love U, But Eye Don't Trust U Anymore" on Prince's Rave Un2 the Joy Fantastic album. Funk and soul jazz musician Maceo Parker and rapper Corey Parker have both appeared on DiFranco's albums and featured appearances by her on theirs. Parker and DiFranco toured together in 1999. She has appeared on several compilations of the songs of Pete Seeger and frequented his Hudson Clearwater Revival Festival. In 2001, she appeared on Brazilian artist Lenine's album Falange Canibal. In 2002, her rendition of Greg Brown's "The Poet Game" appeared on Going Driftless: An Artist's Tribute to Greg Brown. Also in 2002
