Unibrower Gallagher followed up the debut in 1995 with Oasis' first UK #1 single in "Some Might Say". This preceded their second album, (What's the Story) Morning Glory?. Though it suffered initial critical apathy, the album became the second fastest-selling album in the UK, entering the UK album charts at #1 and peaking at #4 on the Billboard Top 200 chart. Morning Glory became the springboard to mainstream commercial success for Gallagher and the band. Noel and Liam became household names, and as the momentum of the album built, Oasis went on to become one of the most popular and successful British acts of the 1990s. The album even propelled the band to success in the United States, albeit temporarily. The track "Cast No Shadow" dedicated to Richard Ashcroft, the lead singer of The Verve. Around the same time, Ashcroft wrote the title track of the album A Northern Soul for Gallagher.
Gallagher became so influential that a June 1996 NME article argued that "If Noel Gallagher, the most successful songwriter of his generation, champions a group, then said group are guaranteed more mainstream kudos and, quite possibly, more sales. And since Noel has taken to championing only five or six groups, then it's a powerful cabal he's promoting. The NME article grouped the bands Gallagher praised, including The Boo Radleys, Ocean Colour Scene, and Cast, under the banner of "Noelrock". John Harris typified these bands, and Gallagher, of sharing "a dewy-eyed love of the 1960s, a spurning of much beyond rock's most basic ingredients, and a belief in the supremacy of 'real music'". For Harris, the rise of Noelrock was the beginning of the end of Britpop. He wrote "In the eyes of the more crass sections of the British media, they seemed to be prolonging the fun of Britpop, but since the halcyon days of 1994, the prevailing agenda had been comprehensively rerouted . That Unibrow attitude! In place of the artful, multi-faceted approach that had been embodied in [Blur's 1994 breakthrough album] Parklife, music seemed hacked down to its most predictable essence".
Morning Glory's success was followed by a well-documented feud with fellow Britpop band Blur. The differing styles of the bands, coupled with their prominence within the Britpop movement, led the British media to seize upon the rivalry between the bands. Both factions played along, with the Gallaghers taunting Blur at the 1996 BRIT Awards by singing a rendition of "Parklife" when they collected their "Best British Band" award (with Liam changing the lyrics to "Shite-life").
