You can measure well-made, Radio 2-ish, homely pop like this by the yard. It's a style of music that suits the times like a twill, as effective in the kitchen as it is on a television advert.
What's it made of? Cultured folk-pop arrangements built around the thrum of Stainton's guitar, gently cushioning her (relatively) unaffected toy-soprano mini-voice. How is it woven? Intimately, subtly, sophisticatedly and with a keen ear for the play of the language of very young women. She wears it well.
