Oasis were an English rock band formed in Manchester in 1991. Originally known as the Rain, the group initially consisted of Liam Gallagher , Paul Arthurs , Paul McGuigan and Tony McCarroll . Liam’s older brother Noel later joined as a fifth member, finalising the group’s core lineup. During the course of their existence, they had various lineup changes, with the Gallagher brothers remaining the only staple members. Oasis signed to independent record label Creation Records in 1993 and released their record-setting debut album Definitely Maybe , which quickly became the fastest-selling debut album in British history at the time. The following year they recorded Morning Glory? with new drummer Alan White, in the midst of a chart rivalry with peers Blur. Spending ten weeks at number one on the UK Albums Chart, Morning Glory? was also an international chart success and became one of the best-selling albums of all time. In addition, it stands as the fifth-best-selling album in the UK and the biggest-selling album in the UK of the 1990s. The Gallagher brothers featured regularly in tabloid newspapers for their disputes and wild lifestyles. In 1996, Oasis performed two nights at Knebworth for an audience of 125,000 each time, the largest outdoor concerts in UK history at the time. In 1997, Oasis released their third album, Be Here Now. It became the fastest-selling album in UK chart history. Oasis’ popularity later declined and McGuigan and Arthurs left in 1999 as Oasis released Standing on the Shoulder of Giants . They were replaced by former Heavy Stereo guitarist Gem Archer and former Ride guitarist Andy Bell. White departed in 2004, replaced by Zak Starkey and later Chris Sharrock as touring members. Oasis released three more studio albums, Heathen Chemistry , Don’t Believe the Truth and Dig Out Your Soul . The group abruptly disbanded after the departure of Noel Gallagher in August 2009. As of 2009, Oasis had sold over 70 million records worldwide. They are among the most successful acts on the UK Singles Chart and Albums Chart, with eight UK number-one singles and eight UK number-one albums. The band also achieved three Platinum albums in the US. They won 17 NME Awards, nine Q Awards, four MTV Europe Music Awards and six Brit Awards, including one in 2007 for Outstanding Contribution to Music and one for the “Best Album of the Last 30 Years” for Morning Glory?. They were nominated for two Grammy Awards.
