“The young and silver toned soprano Teresa Castillo pleased the audience with two beautifully interpreted songs from the mid 20th century pop standard world that begged to be sung by a lyric voice: “Luna Liberiana” by Jesus Bomilla from Costa Rica was a mix of jazz and French impressionism; “El Faisan” by Lecuona climbed to a higher tessitura that showed off Ms. Castillo's voice to great advantage.”
