Joan Baez in the context of "Bob Dylan"

Contemporary folk music refers to a wide variety of genres that emerged in the mid-20th century and afterwards which were associated with traditional folk music. Starting in the mid-20th century, a new form of popular folk music evolved from traditional folk music. This process and period is called the (second) folk revival and reached a zenith in the 1960s. The most common name for this new form of music is also "folk music", but is often called "contemporary folk music" or "folk revival music" to make the distinction. The transition was somewhat centered in the United States and is also called the American folk music revival. Fusion genres such as folk rock and others also evolved within this phenomenon. While contemporary folk music is a genre generally distinct from traditional folk music, it often shares the same English name, performers and venues as traditional folk music; even individual songs may be a blend of the two.

While the Romantic nationalism of the first folk revival had its greatest influence on art music, the "second folk revival" of the later 20th century brought a new genre of popular music with artists marketed through concerts, recordings and broadcasting. One of the earliest figures in this revival was Woody Guthrie, who sang traditional songs in the 1930s and 1940s as well as composing his own. Other major performers who emerged from the 1940s to the early 1960s included Pete Seeger, Bob Dylan, Joan Baez, Peter, Paul and Mary, Phil Ochs and Tom Paxton. In the UK, the folk revival fostered a generation of musicians such as Fairport Convention, Richard Thompson, Donovan, Martin Carthy, and Pentangle, who achieved initial prominence in the 1960s. The folk revival spawned Canada's first folk wave of internationally successful artists such as Neil Young, Gordon Lightfoot, Leonard Cohen, Joni Mitchell, and Buffy Sainte-Marie.

The American folk music revival began during the 1940s and peaked in popularity in the mid-1960s. Early folk music performers include Woody Guthrie, Lead Belly, Pete Seeger, Richard Dyer-Bennet, Oscar Brand, Jean Ritchie, John Jacob Niles, Susan Reed, Mississippi John Hurt, Josh White, and Cisco Houston. Lead Belly recorded "Cotton Fields" and "Goodnight, Irene" and folk singer Odetta released folk albums.

New folk musicians such as Bob Dylan, Joan Baez, Judy Collins, Joni Mitchell, Phil Ochs, Peter Paul & Mary and many others recorded folk songs and new compositions in the folk style in the 1960s and 1970s. The revival also brought forward strains of American folk music that had in earlier times contributed to the development of country and western, bluegrass, blues, and rock and roll music.

Sacco & Vanzetti (Italian: Sacco e Vanzetti) is a 1971 historical legal drama film, based on the trial of Italian-American anarchists Nicola Sacco and Bartolomeo Vanzetti, whose guilty verdict and execution was considered a politically-motivated miscarriage of justice. The film is directed and co-written by Giuliano Montaldo, and stars Gian Maria Volonté and Riccardo Cucciolla in the title roles. The cast also features Cyril Cusack, Milo O'Shea, Geoffrey Keen and Rosanna Fratello.

An Italian and French co-production, the film is mainly shot in color although it both starts and finishes in black and white, and also includes period black and white newsreels. The musical score was composed and conducted by Ennio Morricone with the three-part ballad sung by Joan Baez.

Thomas Richard Paxton (born October 31, 1937) is an American folk singer-songwriter whose career spans more than sixty years. In 2009, Paxton received a Grammy Lifetime Achievement Award. He is a music educator as well as an advocate for folk singers to combine traditional songs with new compositions.

Paxton's songs have been widely recorded, including modern standards such as "The Last Thing on My Mind", "Bottle of Wine", "Whose Garden Was This", "The Marvelous Toy", and "Ramblin' Boy". Paxton's songs have been recorded by Pete Seeger, Bob Dylan, the Weavers, Judy Collins, Sandy Denny, Joan Baez, Doc Watson, Harry Belafonte, Peter, Paul and Mary, the Seekers, Marianne Faithfull, the Kingston Trio, the Chad Mitchell Trio, John Denver, Dolly Parton and Porter Wagoner, Johnny Cash, Willie Nelson, Flatt & Scruggs, the Move, the Fireballs, Francesco Guccini and many others (see covers).

John Jacob Niles (April 28, 1892 – March 1, 1980) was an American composer, singer and collector of traditional ballads. Called the "Dean of American Balladeers," Niles was an important influence on the American folk music revival of the 1950s and 1960s, with Odetta, Joan Baez, Burl Ives, Peter, Paul and Mary and Bob Dylan, among others, recording his songs.

Odetta Holmes (December 31, 1930 – December 2, 2008), known as Odetta, was an American singer, often referred to as "The Voice of the Civil Rights Movement". Her musical repertoire consisted largely of American folk music, blues, jazz, and spirituals.

An important figure in the American folk music revival of the 1950s and 1960s, she influenced many of the key figures of the folk-revival of that time, including Bob Dylan, Joan Baez, Mavis Staples, and Janis Joplin. In 2011 Time magazine included her recording of "Take This Hammer" on its list of the 100 Greatest Popular Songs, stating that "Rosa Parks was her No. 1 fan, and Martin Luther King Jr. called her the queen of American folk music."
