Given the question: Information: - Hard rock is a loosely defined subgenre of rock music that began in the mid-1960s, with the garage, psychedelic and blues rock movements. It is typified by a heavy use of aggressive vocals, distorted electric guitars, bass guitar, drums, and often accompanied with pianos and keyboards. - Newcastle upon Tyne, commonly known as Newcastle, is a city in Tyne and Wear, North East England, 103 miles (166km) south of Edinburgh and 277 miles (446km) north of London on the northern bank of the River Tyne, from the North Sea. Newcastle is the most populous city in the North East and forms the core of Tyneside conurbation, the eighth most populous urban area in the United Kingdom. Newcastle is a member of the English Core Cities Group and is a member of the Eurocities network of European cities. Newcastle was part of the county of Northumberland until 1400, when it became a county of itself, a status it retained until becoming part of Tyne and Wear in 1974. The regional nickname and dialect for people from Newcastle and the surrounding area is Geordie. Newcastle also houses Newcastle University, a member of the Russell Group, as well as Northumbria University. - The Beatles were an English rock band, formed in Liverpool in 1960. With members John Lennon, Paul McCartney, George Harrison and Ringo Starr, they became widely regarded as the foremost and most influential act of the rock era. Rooted in skiffle, beat, and 1950s rock and roll, the Beatles later experimented with several musical styles, ranging from pop ballads and Indian music to psychedelia and hard rock, often incorporating classical elements and unconventional recording techniques in innovative ways. In the early 1960s, their enormous popularity first emerged as "Beatlemania", but as the group's music grew in sophistication, led by primary songwriters Lennon and McCartney, they came to be perceived as an embodiment of the ideals shared by the counterculture of the 1960s. - Metallica is an American heavy metal band formed in Los Angeles, California. The band was formed in 1981 when vocalist/guitarist James Hetfield responded to an advertisement posted by drummer Lars Ulrich in a local newspaper. Metallica's current line-up comprises founding members Hetfield and Ulrich, longtime lead guitarist Kirk Hammett and bassist Robert Trujillo. Guitarist Dave Mustaine and bassists Ron McGovney, Cliff Burton and Jason Newsted are former members of the band. - Market Harbour is a solo album by The Wildhearts frontman Ginger , released in January 2008 on Round Records . - Pop music is a genre of popular music that originated in its modern form in the Western world as a softer alternative to rock and roll. The terms "popular music" and "pop music" are often used interchangeably, although the former describes all music that is popular and includes many styles. "Pop" and "rock" were synonymous terms until the late 1960s, when they were increasingly used in opposition from each other. - The Wildhearts are an English rock group, formed in 1989 in Newcastle upon Tyne. The band's sound is a mixture of hard rock and melodic pop music, often described in the music press as combining influences as diverse as The Beatles and 1980s-era Metallica. However, this characterization is denied by the band, who see their influences as being far broader, as shown in the song "29 X The Pain", which lists many of group leader Ginger's influences. Despite several top 20 singles and one top 10 album in Britain, the Wildhearts have not achieved major commercial success, owing in part to difficulties with record companies and many internal problems often relating to recreational drugs and depression. Much of the band's early career was affected by bitter feuds with their record company, East West.
