at two outdoor concerts on December 16 and 17, 2011 on the grounds of the Castillo (Fort) San Felipe del Morro ("El Morro"), a UNESCO World Heritage Site in San Juan, Puerto Rico. The recorded concerts were broadcast on PBS beginning in March 2012, the production constituting Yanni's tenth collaboration with that organization. Yanni performed again in China in the February 9, 2013, CCTV Spring Festival Gala (annual audience 700 million) with Chinese zither artist Chang Jing in what was the first year that CCTV had invited foreign artists to perform. For the performance, Yanni released a single "East Meets West" which was a mashup of his several famous songs (Santorini, North Shore of Matsushima) together with a solo part performed on Chinese zither. Yanni's 2010s tours included new vocalists, distinct from the 2008–2009 Yanni Voices vocalists, though the setlists remained predominantly instrumental. In March 2014, Yanni released his seventeenth studio album, Inspirato, a collaboration with operatic tenor Plácido Domingo and producer Ric Wake that, like Yanni Voices five years earlier, highlighted vocal performances. In Inspirato, distinguished operatic vocalists performed remakes of songs that Yanni had previously released over his career, the songs' titles and lyrics being predominantly in the Italian language. In March 2015, Yanni released the title soundtrack for a Chinese documentary movie Hexi Corridor. On October 30 and 31, 2015, Yanni performed two concerts on the grounds of the Egyptian pyramids and Great Sphinx of Giza, his first performance in Egypt. The concerts included fireworks and a video broadcast from International Space Station commander Scott Kelly, and were recorded in 4K HD for subsequent broadcast on PBS. To convey an image of stable security after the Egyptian Crisis (2011–14), an Egyptian security force of 3,000 people secured the concert area. In December 2015, Yanni produced a song, "Seven Billion Dreams," for a NASA video that marked the 15th anniversary of the International Space Station. On December 18, 2015, Yanni released the single "Desert Soul" from his eighteenth studio album, Sensuous Chill, which was released on January 29, 2016. The album, which, being built around synthesizers, programmed rhythms and electronic sounds, was said to "come full circle" to his early-1980s albums. Yanni's single, "When Dreams Come True", called a "minimal piano-led" piece, was composed incrementally throughout a 60-date North American tour as a series of improvisations performed during successive shows. Its first complete live performance was in February
