It's a minor miracle that Eliza Doolittle, the 22-year-old Camdenista, has managed to make such a coherent and effortless-sounding debut album. Although she has co-written every song, she's done so alongside 11 other writers, with additional credits going to the Fleetwoods for the sample of their 1959 song Come Softly to Me, and to George and Felix Powell for lifting their chorus to Pack Up Your Troubles in Your Old Kit-Bag. The vintage of those steals indicates the musical tone: retro-modern, a collage of familiar summery styles – a little ska here, some Cuban rhythms there – simmered into something unmistakably of this age. It's a delicious soufflé – the hooks of Moneybox, Skinny Genes, Pack Up and Missing are irresistible – that feels as light as air, melting on your tongue. Admittedly, that also means that as soon as it is over it has disappeared without a trace, but do picnic soundtracks really need to be weighed down with pretensions to significance?
