Interview with Anoushka Shankar by phone to Washington D.C. on March 31, 2016, the day before the beginning of a month-long tour for her new album Land of Gold, inspired by the current refugee crisis. The varied elements of Land of Gold grew “from the ground up,” says Shankar, and represent a new level of artistic strength and truth. At foundation is the quartet of sitar, double-bass (Larry Grenadier), shehnai (Sanjeev Shankar) and hang drum (Manu Delago). Vocal appearances include M.I.A. in an electronica-rap track; singer-songwriter Alev Lenz with lyrics and voice for the title song; and actress Vanessa Redgrave delivering a powerful reading of a new poem by Pavana Reddy about belonging and resilience. Shankar brought her quartet to Campbell Hall on Monday April 11 at 8pm, courtesy of UCSB Arts & Lectures.
