Folksongs of Illinois is a series of three CDs that document the rich and varied history of folk and popular music in Illinois. The CDs feature songs from a broad range of talented Illinois musicians and include recordings taken from archival, 78 rpm, LP, and contemporary CD recordings, as well as new studio recordings. The music includes traditional folk ballads, polkas, early country tunes, corridos, gospel hymns, labor anthems, Irish reels, and tamburitza kolos. Listeners can hear the legendary violinist Johnny Frigo, polka king Little Wally, "alt country" favorites Jon Langford, Kelly Hogan, and Janet Bean, and All-Ireland Champion fiddler Liz Carroll, as well as Grammy winner Alison Krauss, gospel great Mahalia Jackson, and early country stars The Girls of the Golden West.
