Grime motormouth Harrison “Aitch” Armstrong was a star before he left his teens. The baby-faced Manchester rhyme-spitter exploded after his delirious, chorus-free rap spree “Straight Rhymez” hit the internet in 2018. Contrary to the melodic leanings of modern rap, Aitch rhymes in lively, wildly cocky clouds of words about stealing girls and getting paid. His style is versatile enough to light up tracks by pop star Ed Sheeran and London drill rappers Russ & Tion Wayne alike. He’s bounded onto the charts with his own singles and collaborations with artists like Bugzy Malone and Young T & Bugsey.
