Sarah Olivar teaches flamenco at the Lido on Wednesdays. She has a strong following, supports local festivals (like the Windmill in Brixton). Wonderful class, great teacher, and at Brockwell Lido. She also runs Flamenco Olivar, a London-based contemporary flamenco dance instruction company that "combines choreographic sophistication with authentic flamenco puro".
