The indie singer-songwriter finds a beautiful world between the comforting and the surreal. Train on the Island is like one of those dreams where strange things happen quietly and as a matter of course: Your house is an abandoned factory but also your old preschool; you find yourself in a foreign country, confidently speaking a language you don’t know. Superficially, Aldous Harding makes the kind of slightly quirked-up indie pop you can hear in coffee shops from Cape Town to Houston and back. But listen closer to Train on the Island and you’ll find a songwriter whose decisions—lyrically, sonically, conceptually—often tilt into the surreal, from the hypnotic repetitions of “If Lady Does It” to the way the title track keeps veering toward silence. Think Feist’s mysterious kid sister.
