“I’m high end, you’re high street,” snarls Tinie Tempah on Demonstration's bouncy, bassy Diplo-poduced stand-out “Trampoline”. He’s not wrong: his ascension from 2011’s cocky prince regent with “so many clothes I keep some in my aunt’s house” to debonair king of London’s fashion scene is mighty impressive and detailed confidently here. “Don’t Sell Out” is a Bollywood-spirited warning about the lure of this big time, “Children of the Sun”’s foreboding electro is set off by a hopeful hook, while “Mosh Pit” pits Tinie against fellow UK heavyweight Dizzee Rascal in a gritty, grimy battle royale.
