Imagine a mix of the art school elegance of Phoenix, the lively melodics of Feist and the emotional depth of Bon Iver. But to draw such comparisons is superficial and not especially helpful because what you miss is the originality of the BOY concept and the charisma of its two performersBOY - a contagious confection that has spread across the internet like wildfire. The Hamburg-based duo gets your toes tapping, mind playing, feet moving, emotions travelling, head thinking, hips jerking. But above all, they make music that brings a smile to your face. BOY are both girls. Valeska Steiner sang in several bands in her native Switzerland before moving to Germany, where Sonja Glass grew up, playing the cello in classical orchestras as a child, and later working as a bass player for several pop bands. The duo met when Valeska won a place at a prestigious summer holiday music workshop in Hamburg. There she met Sonja, who had recently returned from a spell studying bass guitar in Holland.BOY's debut album, "Mutual Friends", is an autobiographical affair. "It's about arrivals and new beginnings," says Valeska, whose songs are written and sung in English. "About hopes and dreams and aspirations. We want to make music that's positive and hopeful," explains Valeska,. "There is more to music than heartbreak and loss," agrees Sonja. The dozen songs on "Mutual Friends", painstakingly recorded over a two-and-a-half year period at the 12 square meter home studio of producer and multi-instrumentalist Philipp Steinke in Berlin, have gone through many transformations since they were written. "We made about 10 versions of most of the songs," says Sonja. "So they have evolved over the course of time. And some of them have ended up sounding completely different from the way they began." BOY played most instruments on the record themselves. Only in some cases, such as drumming duties, a rotating roster of friends jumped in to play, among them Phoenix's live drummer Thomas Hedlund.
