Containing every track from every Who single and EP, this hefty collection is a fascinating way to chart the band's evolution. With the A-sides, you can mark the progression from the clangorous youth rebellion of "My Generation" to the street-savvy arena rock of "Won't Get Fooled Again" and the funky, synth-flecked "Eminence Front." But the B-sides offer endless surprises, like the gritty, almost Captain Beefheart-esque 1965 cover of blues tune "Bald Headed Woman," or the cabaret psychedelia of the spooky John Entwistle-sung "Dr Jekyll & Mr Hyde."
