With their single 'Under' now over 1m views and garnering them serious attention last summer, South London duo A O S S O N are back with 'High Grade', a track that is sure to reach similar heights. A shining tune shimmering with the potential of summer romances, it's understandable why the pair have such a universal appeal as lead singer Marisa Hylton's voice couples so well with Manny Folorunso's tropical acoustic bed. There are hints of reggae in the mix as a nod to their hero Bob Marley, and we can see this one soundtracking all of the summer BBQ's this year. 'High Grade' gets a A+ from us. - SJ
