Once they'd made their explosive breakthrough with 2005's “I Bet You Look Good on the Dancefloor”, Arctic Monkeys' ascent to Glastonbury-headlining alt-rock nobility seemed assured. As predictable as it was, it's been a thrilling rise—executed with adventure and confidence. After the stirring garage-rock vignettes of debut Whatever People Say I Am, That's What I'm Not and 2007's Favourite Worst Nightmare, each subsequent album has delivered increasingly assured forays into new sonic territories. They've given us Josh Homme-assisted desert-rock (“Crying Lightning”), psychedelic pop (“Black Treacle”), Motown ("Snap Out of It") and G-Funk ("Why'd You Only Call Me When You're High?”). Throughout, the constant has been Alex Turner's lyricism: kitchen-sink poetry littered with arid wit, pin-sharp cultural observations and compelling personal insight.
