Blur 21

The release took place before the band's performance at Hyde Park as part of the 2012 Summer Olympics closing ceremony.

One version of the box-set consists of eighteen CDs, three DVDs, one vinyl 7" record (of the early Seymour track "Superman") and a hardcover book acting as a complete biography of the band.

Additionally, no material from the band's 1998 live recording and remix album Bustin' + Dronin' appears on the box set.

Rarities 4, one of the bonus albums in the box set, features an early mix of "Under the Westway" with some differences between it and the 2012 single version.

[2] Stephen Thomas Erlewine of AllMusic wrote, "There were plenty of other great British bands of the '90s but none of their peers – Oasis, Suede, Pulp, Radiohead – covered as much stylistic ground or wound up with a catalog as rich as this ridiculously generous box set handily proves.
