Costa Rican Baroque violinist and scholar Guillermo Salas-Suárez performs with several period ensembles in North America, including the Lyra, Atlanta and North Carolina Baroque Orchestras, Apollo’s Fire, The Newberry Consort, Sound Salon, Lumedia Mu  sicWorks, Bach Collegium Fort Wayne, etc. He has also served as guest concertmaster with the Indianapolis Baroque Orchestra, Bourbon Baroque, and the American Baroque Opera Co. Guillermo holds a Doctorate of Musical Arts in Historical Performance from Case Western Reserve University, where he studied with Dr. Julie Andrijeski. Guillermo’s chamber music appetite spans from the Renaissance and Baroque periods, which he explores with The Early Interval, up to the Classical and early Romantic repertoire for string quartet and clarinet with Wit’s Folly, which he co-founded. He has collaborated and trained with Malcolm Bilson, Paolo Pandolfo, Jaap ten Linden, Barthold Kuijken, Bruce Dickey, and the late Jeanne Lamon at the early music festivals in Boston, Bloomington, Amherst, Bach Oregon, Urbino (Italy), Daroca (Spain), Saintes (France), and the Stuttgart Bachwoche (Germany).

As a scholar of Spanish and colonial music, he has presented his research in conferences at Boston, Indiana, Oregon Universities, and Universidad Nacional Autónoma de México. His upcoming book The Tender Echo, a commented English translation of the Spanish violin treatises from the 18th century, is currently under publishing contract with Indiana University Press. As an educator, Guillermo is committed to the advancement of historical performance practice in Latin America. He served on the faculty of the Festival de Musica de Santa Catarina (Brazil), and has conducted masterclasses and workshops at the Academia de Música Antigua de Medellín (Colombia), Escuela Nacional de Música (Honduras), Universidad Nacional, Instituto Nacional de Música (Costa Rica), etc. He also serves in Early Music America’s IDEA Task Force, dedicated to promoting diversity and inclusion in early music throughout the Americas.

René Schiffer was born in the northern part of the Dukedom of Brabant, in Bach’s era part of the Republic of the Seven United Netherlands. He studied in Amsterdam with Anner Bijlsma, then specialized in historical performance with Jaap ter Linden. In Oberlin, he studied the viola da gamba with Catherina Meints, to whom he dedicated his Concerto for Two Viols (under the name Katharina von Mainz).  Master Schiffer performed with groups like La Petite Bande, Ensemble Gare de Lyon, Tafelmusik Baroque Orchestra, Les Musiciens du Louvre, the Netherlands Bach Society, occasionally with Concerto Armonico, the Amsterdam Baroque Orchestra. He has been principal cellist for Apollo’s Fire since its foundation in 1992. He has played recitals and solo performances with orchestras in Budapest, Paris, Versailles, Utrecht, Brôme (there’s nothing wrong with playing Uccellini in Brome), Chautauqua, Tanglewood, Ravinia, and Grandchamp. On two occasions he asked the way to Carnegie Hall, but did not have the good fortune to get the answer Practice!  Schiffer has taught at Case Western, Cleveland Institute of Music, at Oberlin, and as guest at several colleges over the United States, including Duke, Dartmouth, and Penn State. He has given talks about music in Toledo and in Cleveland for Apollo’s Fire’s subscription series. So far, Schiffer has mastered the cello, the historical cello, the bass viol, the (French) bass violin, the violoncello piccolo in at least three different tunings, and the G-violone, that’s a violone while wearing a thong with a G string. I think he shares a Grammy Award with Apollo’s Fire’s musicians and the incomparable Karim Hunt, correction, Sulayman.  He is also very good at declaiming and driving really long distances.  As composer Schiffer, sometimes under names like René Antoine Duchiffre, Renato Marini, Captain Hummus and Johann Sebastian Offenschiffer, can be heard on Apollo’s Fire’s Vivaldi & Friends CD, where his Tango Concerto is featured. A video of the tango of that concerto can also be enjoyed on Youtube. His Clorinda Sonata and his Jewish Rhapsodies (Ovos, Kaddish and Olenu) also feature on that channel. Among works that are awaiting recording are his Variations on themes from Ortiz’ Tratado, two Abel arrangements for 5-string cello and his Christmas Medley. He wrote two “Bach suites”: the 7th suite in D, BMW 1013 (in the 1990s) and the more recent Kronstadter Partita, BMW 17465, a fairly late work. Schiffer just purchased a historical bow from Stephen Marvin. With his angel Marie Rowley, he resides in Chagrin Falls.

Lauded by Cleveland Classical as "an excellent soloist, a compelling performer who is equally comfortable handling long strings of notes... and singing through emotive melodies with her instrument,” Dr. Qin Ying Tan currently serves as harpsichord faculty at Baldwin-Wallace Conservatory of Music. As co-artistic director of The Resonance Project Cleveland and CLE Concierto, Dr. Tan has helped lead a highly successful inaugural season, marked by sold-out premium seating and critical acclaim for its bold programming, intimate performances, and unwavering commitment to musical excellence. Together with pianist Irwin Shung, they have brought fresh energy to Cleveland’s classical music scene by fostering cross-cultural collaborations and reimagining the concert experience for 21st-century audiences.

Dr. Tan has appeared in concerts in Singapore, Shanghai, Germany, France, and has performed extensively across the United States of America.  This season sees engagements with Hudson Historical Society and Library, City Music, the Historically-Informed Performance Practice Department at Case Western Reserve University, and the Baldwin-Wallace Bach Festival.  In addition to her commitment to early repertoire, Tan regularly presents new music to her audiences and has premiered several pieces, most notably Cenk Ergun's sound installation piece, "Fomare" at the Cleveland Museum of Art and “Are You You” by Michi Wiancko with City Music.   As a pedagogue, Dr. Tan’s students have successfully gained admission into graduate programs in Michigan and Boston.  Dr. Tan continues to cultivate an interest in historically-informed performance at the pre-college and college level in her role as a board member of the Northeast Ohio MTNA and harpsichord faculty at Baldwin Wallace Conservatory.  Her passion for sharing historical music has also led her to lead dynamic workshops on baroque dance and historical keyboards in Southeast Asia where accessibility to period music is rare.  When not at work, Ying loves exploring and hiking around beautiful Cleveland with her family. She welcomes conversations about culture, history or how music can be a vehicle for social change and a tool to bring communities together.
