Caster Singer & Kammerstreicher String Chamber Orchestra – 3pm
Magical strings & beautiful voices combine to perform an eclectic selection of music from Gershwin to spirituals & Toto's 'Africa'
The highly talented Kammerstreicher String Chamber Orchestra and Castle Singers, both from Wartburg College in Waverly, Iowa, have come together as part of a 21-day tour throughout Europe, performing in Eisenach, Prague, Vienna, Ljubljana, Split, Dubrovnik and London. Performance highlights will include American works by Gershwin, traditional spirituals, classical and contemporary pieces by Toto’s ‘Africa’ and Sam Cook’s ‘What a Wonderful World’.
The name Kammerstreicher is a nod to Wartburg’s rich German heritage—Kammerstreicher means “chamber strings”—and also stems from a desire of the group to reshape expectations for what a chamber orchestra can be and do. Dr. Rebecca Nederhiser is a passionate conductor, scholar, and oboist. In addition to Kammerstreicher, Nederhiser also leads the Wartburg Community Symphony and teaches music theory, oboe, and conducts at Wartburg College.
Under the direction of Dr. Nicki Bakko Toliver, Castle Singers are composed of advanced vocalists who are dedicated to exploring challenging choral literature. The Castle Singers travel extensively and previous international tours include countries throughout Western and Eastern Europe, Scandinavia, the Middle East, the Caribbean, Latin America, Australia and French Polynesia.
The choir and orchestra with piano accompaniment will be joined by guest soloist Dr. Gabriel Forero, on the viola. Originally from Bogotá, Colombia, Gabriel is an active solo, chamber, orchestral and Baroque performer.
Don’t miss out on this incredible opportunity to enjoy live music in a stunning venue. See you there!
