Squirrel Nut Zippers is an American swing and jazz band formed in 1993 in Chapel Hill, North Carolina, by James "Jimbo" Mathus (vocals and guitar), Tom Maxwell (vocals and guitar), Katharine Whalen (vocals, banjo, ukulele), Chris Phillips (drums), Don Raleigh (bass guitar), and Ken Mosher.
The band's music is a fusion of Delta blues, gypsy jazz, 1930s–era swing, klezmer, and other styles. They found commercial success during the swing revival of the late 1990s with their 1996 single "Hell", written by Tom Maxwell. After a hiatus of several years, the original band members reunited and performed in 2007, playing in the U.S. and Canada.
In 2016, Mathus and Phillips reunited the band with a new lineup to tour in support of the 20th anniversary of their highest selling album, Hot.
The Squirrel Nut Zippers continue to tour, and released their new album, Beasts of Burgundy in March 2018, and singles "Mardi Gras for Christmas" and "Alone at Christmas" in November 2018.
