8. Blur, '21'
Britpop is not a big enough word to cover the ambition and pop-smart achievement in this career summation: seven studio LPs and an ocean of extras across 21 discs. Blur's main competition, Oasis, pinched heavily from the Beatles; Blur changed and matured with Beatles-like velocity, from the shoe-gazer psychedelia of 1991's Leisure and the modern-Kinks irony on 1994's Parklife to the hip-hop nerve of 2003's Think Tank. You can get the original albums in separate two-CD sets – a good value – but this box is the entire story. It is not overkill.
