Sarah Ann McLachlan, OC, OBC (born January 28, 1968) is a Canadian musician, singer and songwriter. Known for her emotional ballads and mezzo-soprano vocal range, as of 2009, she has sold over 40 million albums worldwide. McLachlan's best-selling album to date is Surfacing, for which she won two Grammy Awards (out of four nominations) and four Juno Awards. In addition to her personal artistic efforts, she founded the Lilith Fair tour, which showcased female musicians. The Lilith Fair concert tours took place from 1997 to 1999, and resumed in the summer of 2010. Since 2006 she has also been known as a highly visible supporter of the ASPCA, as well as various other charities.

Sarah McLachlan was born on January 28, 1968, and adopted in Halifax, Nova Scotia, Canada. As a child, she took voice lessons, along with studies in classical piano and guitar. When she was 17 years old and still a student at Queen Elizabeth High School, she fronted a short-lived rock band called The October Game. One of the band's songs, "Grind", credited as a group composition, can be found on the independent Flamingo Records release Out of the Fog and the CD Out of the Fog Too. It has yet to be released elsewhere. Her high school yearbook predicted that she was "destined to become a famous rock star."

Neil Percival Young,OC,OM (born November 12, 1945) is a Canadian singer-songwriter who is widely regarded as one of the most influential musicians of his generation.

Young began performing as a solo artist in Canada in 1960, before moving to California in 1966, where he co-founded the band Buffalo Springfield along with Stephen Stills and Richie Furay, and later joined Crosby, Stills & Nash as a fourth member in 1969. He forged a successful and acclaimed solo career, releasing his first album in 1968; his career has since spanned over 40 years and 34 studio albums, with a continual and uncompromising exploration of musical styles. The Rock and Roll Hall of Fame website describes Young as "one of rock and roll’s greatest songwriters and performers". He has been inducted into the Hall of Fame twice: first as a solo artist in 1995, and second as a member of Buffalo Springfield in 1997.

Young's work is characterized by his distinctive guitar work, deeply personal lyrics and signature alto or high tenor singing voice. Although he accompanies himself on several different instruments, including piano and harmonica, his idiosyncratic electric and clawhammer acoustic guitar playing are the defining characteristics of a varyingly ragged and melodic sound. While Young has experimented with differing music styles, including swing and electronic music throughout a varied career, his best known work usually falls into two primary styles: acoustic (folk and country rock) and electric (amplified hard rock, very often in collaboration with the band Crazy Horse). Young has also adopted elements from newer styles such as alternative rock and grunge. His influence on the latter caused some to dub him the "Godfather of Grunge".
