Urban was born in New Zealand and began his career in Australia at an early age. In 1991, he released a self-titled debut album, and charted four singles in Australia before moving to the United States in 1992. Eventually, Urban found work as a session guitarist before starting a band known as The Ranch, which recorded one studio album on Capitol Records and charted two singles on the Billboard country charts.

Still signed to Capitol, he made his solo American debut in 1999 with the album Keith Urban. Certified platinum in the U.S., it also produced his first American Number One in "But for the Grace of God". His breakthrough hit was the Number One "Somebody Like You", from his second Capitol album Golden Road (2002).

This album was re-released a year later as Greatest Hits: 19 Kids with one track added: the number one "You Look Good in My Shirt", which he had previously recorded on Golden Road. Additional albums Defying Gravity and Get Closer were released on 31 March 2009 and 16 November 2010, respectively.

James Alan Hetfield (born August 3, 1963) is the rhythm guitarist, co-founder, main songwriter, and lead vocalist for the American heavy metal band Metallica. Hetfield co-founded Metallica in October 1981 after answering a classified advertisement by drummer Lars Ulrich in the Los Angeles newspaper The Recycler, searching for band members. Since then, Metallica has won nine Grammy Awards and released nine studio albums, three live albums, four extended plays and 24 singles. In 2009, Hetfield was ranked number 8 in Joel McIver's book The 100 Greatest Metal Guitarists, and ranked twenty-fourth by Hit Parader on their list of the 100 Greatest Metal Vocalists of All Time.

Hetfield was born August 3, 1963. He is of German, English, Irish and Scottish descent. He has two older half-brothers from his mother's first marriage and one younger sister. He attended Downey High School his freshman and sophomore years.

His father, Virgil, was a truck driver who left the family when Hetfield was young. His mother, Cynthia, was a light opera singer. The two divorced in 1976. Virgil and Cynthia were very strict Christian Scientists, and in accordance with their beliefs, Hetfield's parents strongly disapproved of medicine or any other medical treatment and remained loyal to their faith even as Cynthia was dying from cancer. This upbringing became the inspiration for many of Hetfield's lyrics later in his career with Metallica, such as songs like "The God That Failed".

After purchasing a 1978 Fender Stratocaster copy, Hammett attempted to customize his sound with various guitar parts, eventually buying a 1974 Gibson Flying V. Hammett also took a job at Burger King as a youth before quitting once he saved enough money for his Marshall amplifier.

Hammett's musical interests eventually drew him into the fledgling thrash metal genre.

Exodus was an influential band in the Bay Area thrash movement.

Lars Ulrich ( /ˈʌlrɪk/ UL-rik; Danish: [lɑːs ˈulˀʁæg̊]; born December 26, 1963) is a Danish drummer, and one of the founding members of the American heavy metal band Metallica. He was born in Gentofte, Denmark to an upper-middle class family. A tennis player in his youth, Ulrich moved to Los Angeles, California at age sixteen to pursue his training; though rather than playing tennis, he became a drummer. After publishing an advertisement in a local Los Angeles newspaper called The Recycler, Ulrich met James Hetfield and formed Metallica.

Lars Ulrich was born on December 26, 1963 in Gentofte, Denmark to Torben Ulrich, a tennis player. Saxophonist Dexter Gordon was Ulrich's godfather. In February 1973, Torben obtained five passes for five of his friends to a Deep Purple concert that was being held in the same Copenhagen stadium as one of his tournaments. When it was discovered that one of the friends could not go, their ticket was handed over to the nine year-old Ulrich. The young Ulrich found himself mesmerized by the performance, buying the band's Fireball album the next day. The concert and the album had a considerable impact on Ulrich, inspiring his entrance into the world of rock and roll and later on, heavy metal. As a result of his newfound interest in music, he received his first drum kit from his grandmother at the age of twelve, a Ludwig. Ulrich originally intended to play tennis, and he moved to America in 1980.
