This indie pop group started out on a high note. Its debut was one of the most acclaimed releases of 2009, winning the Mercury Prize and placing near the top on a slew of year-end best-of lists. Last year’s follow-up, Coexist, cemented the British band's signature sound with more moody, mysterious, and minimalistic tracks of guitar, bass, drums, keyboards, and occasional strings. Light vocals flush out elegantly simple songs like “Angels” and “Chained.” Opening act is ethereal pop troupe Hundred Waters. Mon 7 p.m.
