Bianca Maes - guitar, percussion, backup vocals. Bec Langley - vocals, percussion. Preston Perche (sounds like Persh)… is Bianca (biancs, bia, or just b) Maes and Rebecca (bec) Langley. YES they are sisters... Formed in early 2009 in the northern suburb of Preston, Melbourne, Preston Perche is a vibrant duo blending acoustic folk, soul funk and progressive rock to come up with a truly unique mix of their own. The raw combination of guitar and percussion, with lightheartedly serious lyrics highlights this unique and catchy sound.
