Allegra’s debut single ‘All About Us’ sees her rolling across our screens in chunky 80s-style rollerblades, giving us full-on nostalgia whilst her friends ride state-of-the-art hoverboards. It has been storming the Billboard Charts this summer and shows no sign of slowing down any time soon. It’s unsurprising that this infectious and summery single came from a collaboration made in pop heaven – Allegra, a young and upcoming superstar collaborates with music mogul Chris Herbert (creator of the Spice Girls) on her debut track.
