She frequently performed jazz, big band, rock and roll and pop music, on the Broadway stage and in concerts, although she began her career in the 1920s singing blues.

Louis Daniel Armstrong (August 4, 1901 – July 6, 1971), nicknamed Satchmo or Pops, was an American jazz trumpeter and singer. Coming to prominence in the 1920s as an innovative cornet and trumpet player, Armstrong was a foundational influence on jazz, shifting the music's focus from collective improvisation to solo performers. With his distinctive gravelly voice, Armstrong was also an influential singer, demonstrating great dexterity as an improviser, bending the lyrics and melody of a song for expressive purposes. He was also greatly skilled at scat singing, or wordless vocalizing. Renowned for his charismatic stage presence and deep, instantly recognizable voice almost as much as for his trumpet-playing, Armstrong's influence extended well beyond jazz, and by the end of his career in the '60s, he was widely regarded as a profound influence on popular music in general: critic Steve Leggett describes Armstrong as "perhaps the most important American musician of the 20th century."

Joan Chandos Baez (born January 9, 1941 in Staten Island, New York) is a folk singer and songwriter known for her highly individual vocal style. Many of her songs are topical and deal with social issues. She is perhaps best known for her hit "Diamonds & Rust" and her covers of Phil Ochs' "There But For Fortune" and The Band's "The Night They Drove Old Dixie Down", and to a lesser extent,"We Shall Overcome," "Love Is Just A Four-Letter Word" and "Farewell Angelina," "Sweet Sir Galahad" and "Joe Hill" . She remains known for her long relationship with Bob Dylan and her lifelong passion for activism, notably in the areas of nonviolence, civil, human rights and, more recently, the environment. Baez has performed publicly for over 50 years, released over 30 albums and recorded songs in at least eight languages. She is considered a folk singer although her music has strayed from folk considerably after the 1960s, encompassing everything from rock and pop to country and gospel. Although a songwriter herself, especially in the mid-1970s, Baez is most often regarded as an interpreter of other people's work, covering songs by Woody Guthrie, Pete Seeger, Bob Dylan, The Beatles, Jackson Browne, Paul Simon, The Rolling Stones, Stevie Wonder and myriad other artists. In more recent years, she has found success interpreting songs of diverse songwriters such as Steve Earle, Natalie Merchant and Ryan Adams. She has a three-octave vocal range and a distinctively rapid vibrato.

Above all, she was admired for her deeply personal and intimate approach to singing. Critic John Bush wrote that she "changed the art of American pop vocals forever."She co-wrote only a few songs, but several of them have become jazz standards, notably "God Bless the Child", "Don't Explain", and "Lady Sings the Blues". She also became famous for singing jazz standards written by others, including "Easy Living" and "Strange Fruit."

Bob Dylan (born Robert Allen Zimmerman on May 24, 1941) is an American singer-songwriter, author, poet and painter who has been a major figure in popular music for five decades. Much of Dylan's most celebrated work dates from the 1960s, when he became an informal chronicler and a reluctant figurehead of American unrest. A number of his songs, such as "Blowin' in the Wind" and "The Times They Are a-Changin'", became anthems of both the civil rights movements and of the opposition to the Vietnam War. After a lifetime of writing, recording, and performing, Dylan's latest record—his 33rd studio album—Together Through Life was released on April 28, 2009. The album reached the number one spot on both the Billboard 200 chart of top selling albums, and the UK album charts in its first week of release. Dylan's early lyrics incorporated political, social, philosophical, and literary influences, defying existing pop music conventions and appealing widely to the counterculture. While expanding and personalizing musical styles, he has explored many traditions of American song, from folk, blues and country to gospel, rock and roll and rockabilly to English, Scottish and Irish folk music, and even jazz and swing. Dylan performs with the guitar, piano and harmonica. Backed by a changing line-up of musicians, he has toured steadily since the late 1980s on what has been dubbed the "Never Ending Tour". Although his accomplishments as performer and recording artist have been central to his career, his songwriting is generally regarded as his greatest contribution. Throughout his career, Dylan has won many awards for his songwriting, performing, and recording. His records have earned Grammy, Golden Globe, and Academy Awards, and he has been inducted into the Rock and Roll Hall of Fame, Nashville Songwriters Hall of Fame and Songwriters Hall of Fame. In 2008, a "Cultural Pathway" was named in Dylan's honor in his birthplace, Duluth. In 2008, he was awarded a Pulitzer Prize Special Citation for his "profound impact on popular music and American culture, marked by lyrical compositions of extraordinary poetic power."
