Leonard Norman Cohen, CC GOQ (born 21 September 1934) is a Canadian singer-songwriter, musician, poet, and novelist. His work often explores religion, isolation, sexuality, and interpersonal relationships. Cohen has been inducted into the American Rock and Roll Hall of Fame and both the Canadian Music Hall of Fame and the Canadian Songwriters Hall of Fame. He is also a Companion of the Order of Canada, the nation's highest civilian honour.

While giving the speech at Cohen's induction into the Rock and Roll Hall of Fame on 10 March 2008, Lou Reed described Cohen as belonging to the "highest and most influential echelon of songwriters."

Cohen was born on 21 September 1934 in Westmount, Montreal, Quebec, into a middle-class Jewish family. He attended Roslyn Elementary School. His mother, Marsha Klinitsky, of Lithuanian Jewish ancestry, emigrated from Lithuania while his great-grandfather emigrated from Poland. He grew up in Westmount on the Island of Montreal. His grandfather was Lyon Cohen, founding president of the Canadian Jewish Congress. His father, Nathan Cohen, who owned a substantial Montreal clothing store, died when Cohen was nine years old. On the topic of being a Kohen, Cohen has said that, "I had a very Messianic childhood." He told Richard Goldstein in 1967. "I was told I was a descendant of Aaron, the high priest." Cohen attended Westmount High School, beginning in 1948 where he was involved with the Student Council and studied music and poetry. He became especially interested in the poetry of Federico Garcia Lorca. As a teenager, he learned to play the guitar, and formed a country-folk group called the Buckskin Boys. Although he initially played a regular acoustic guitar as a teenager, he soon switched to playing a classical guitar after meeting a young Spanish flamenco guitar player who taught him "a few chords and some flamenco."

Jeffrey Scott "Jeff" Buckley (November 17, 1966 – May 29, 1997), raised as Scotty Moorhead, was an American singer-songwriter and guitarist. He was the son of Tim Buckley, also a musician. After a decade as a guitarist-for-hire in Los Angeles, Buckley amassed a following in the early 1990s by playing cover songs at venues in Manhattan's East Village, such as Sin-é, gradually focusing more on his own material. After rebuffing much interest from record labels and his father's manager Herb Cohen, he signed with Columbia, recruited a band, and recorded what would be his only studio album, Grace.

Over the following two years, the band toured widely to promote the album, including concerts in the U.S., Europe, Japan and Australia. In 1996, they stopped touring and made sporadic attempts to record his second album in New York with Tom Verlaine as producer. In 1997, Buckley moved to Memphis, Tennessee, to resume work on the album, to be titled My Sweetheart the Drunk, recording many four-track demos while also playing weekly solo shows at a local venue. While awaiting the arrival of his band from New York, he drowned during a spontaneous evening swim — fully clothed — in the Wolf River, when he was caught in the wake of a passing boat. His body was found on June 4, 1997.
