Few bands command a festival headline slot the way Arctic Monkeys do, and their 2023 NOS Alive performance on the Portuguese coast is proof of exactly that, opening with the cinematic atmosphere of “Sculptures of Anything Goes” from ‘The Car’ before detonating into “Brianstorm” and never really letting the crowd breathe again.
