Oasis was an English rock band formed by Liam Gallagher, Paul "Bonehead" Arthurs, Paul "Guigsy" McGuigan and Tony McCarroll, who were soon joined by Liam's older brother Noel Gallagher.
They have had eight UK number-one singles and eight UK number-one albums, and won fifteen NME Awards, nine Q Awards, four MTV Europe Music Awards and six Brit Awards. They have been nominated for three Grammy Awards and have sold an estimated 85 million albums worldwide. The band has released seven studio albums, one live album, three compilation albums, two box sets, two extended plays, five video albums and thirty-one singles.
In 1994, the group released their record-setting debut album Definitely Maybe followed by (What's the Story) Morning Glory?. The Gallagher brothers featured regularly in tabloid newspapers for their sibling disputes and wild lifestyles. In 1997, Oasis released their third album, Be Here Now, and although it became the fastest-selling album in UK chart history, the album's popularity tapered off quickly.
The band lost members Paul McGuigan and Paul Arthurs as they went on to record and release Standing on the Shoulder of Giants in 2000 and were replaced by Gem Archer and Andy Bell who joined the group for the tour in support of Giants. The band found renewed success and popularity starting with 2005's Don't Believe the Truth.
In August 2009, Noel Gallagher announced his departure from the band after a backstage altercation with Liam before a festival appearance. The band, comprising the remaining members of Oasis and led by Liam Gallagher, decided to continue working together under the name Beady Eye, while Noel went on to form his solo project Noel Gallagher's High Flying Birds.
