The Rainbow Chamber Singers (RCS) was founded in 2010 by conductor Jin Chengzhi and a small group of his fellow students at the prestigious Shanghai Conservatory of Music. The choir puts on a concert every six months, performing old favorites and newly written traditional-style choral pieces.
Jin -- who describes himself as a "rational optimist" -- said that his work comes from his own experiences and anxieties, but that he hopes the songs "can bring people understanding and hope for life."
