Those not familiar with Twin Sister will notice a flowing, romantic feel to their music. Lead singer Andrea Estella's vocals are sinfully innocent with a heady nod to Stereolab's Lætitia Sadier.
The band's overall sound is of airy pop, but there are some pretty sophisticated workings going on, especially in the song "Milk & Honey." The song's structure quickly breaks off from its slow, lumbering build into a jagged chorus, complete with Estella lamenting "Why can't you be / What I want you to be?" It is a complex, multilayered song that builds towards a hauntingly gleeful refrain, "If you / Love me you would try to," signaling the end of its jam-packed four and a half minutes. And that's just one of the 6 solid tracks on the EP
