‘So I Cry Out’ by Gambles is as simple as music gets: a voice, a few guitar chords and a bucketload of raw emotion. It’s the sort of track that only an experienced artist could possibly have the self-assurance to come up with – except this is Gambles, who sprung from nowhere to take the internet by storm last year with the first song he ever let loose into the world, ‘Trust’. An album, also called Trust, is out next month.
