Few Oasis songs matched the sheer volume of "My Big Mouth." Noel Gallagher later admitted the studio recording became buried beneath layers of distorted guitars, making it one of the densest mixes on Be Here Now. Live, the song took on a different character, its relentless riff cutting through with far greater clarity and power. Performed at Knebworth in 1996 before the album had even been released, it gave the huge crowd an early taste of the louder, more ambitious direction Oasis were about to take.
