Kristin Allen-Zito’s songs are finely tuned, sharply barbed observations on life and love, wrapped up in delicate finger picking and sweetly layered harmonies. Her new album, Helium, marks the arrival of a distinctive new voice and beguilingly fresh take on the singer/songwriter genre. It’s a record filled with small yet telling details - coffee cups, cigarettes, stubbed toes - that become deft metaphors for the heart’s conundrums, complexities and contradictions.
