Wiki says: The group came together at Cardiff University in 2006, originally consisting of Neil Turner on guitar, Ellen Waddell on bass guitar, and Ollie Briggs on drums. In March 2006, Tom Bromley joined the band, assuming the role of lead guitarist, later followed by Gareth Paisey – who became the band's principal lyricist – on lead vocals and glockenspiel, Harriet Coleman on violin and keyboard, and finally Aleksandra Berditchevskaia on vocals, keyboards, and melodica. According to Tom, he met Neil after overhearing him discussing Sufjan Stevens at a club. The band's earliest compositions were long pieces in the style of post-rock, though no recordings from this era are known to circulate publicly. The word campesino in Spanish translates to "peasant" or "country person".
