About the Artists

The Olson/De Cari Duo straddle science and art gloriously.

Science Friday Initiative

The Olson/De Cari Duo, a husband-and-wife ensemble, is dedicated to expanding the repertoire for classical guitar and voice, deriving inspiration from their eclectic backgrounds in both science and the arts.

The Duo’s unique approach to song performance draws on Gioia’s expertise as both a classical singer and a theatre artist, and John’s diverse musical background and affinity for ensemble performance. Their innovative repertoire includes many pieces written for them, including compositions from their Science/Music Commissioning Project, which seeks to celebrate the science-informed worldview and illuminate the human side of science through song. 

NYlon Review described their performance as “superb . . . served up with style and elegance,” and the Science Friday Initiative noted that “the Olson/De Cari Duo straddle science and art gloriously.”

NYlon Review

Their latest CD, Eve’s Diary, features new compositions and arrangements commissioned by the Duo, including song cycles by David Leisner and Frank Wallace, arrangements of Jobim songs by João Luiz, and arrangements of theatre songs by Clarice Assad. The Duo’s debut CD, Quiet Songs, featured the world premiere recording of David Leisner’s song cycle Outdoor Shadows, as well as the first American recordings of John W. Duarte’s Five Quiet Songs and his arrangements of Gershwin songs. According to Urban Guitar, “fresh interpretations . . . make this a CD worth listening to.” For more information about the Duo, visit
