The Siskiyou Institute will present pianist Darrell Grant and fluglehorn player Dmitri Matheny performing music that explores the jazz and classical traditions at 7:30 p.m. Friday, June 25, at the Old Siskiyou Barn in Ashland.

Grant and Matheny made their debut as a duo in 1996 at Carnegie Hall in New York City. Since then, the two have appeared at large concert halls and festivals around the country and recorded with like-minded musicians on many projects.

The pair recorded a debut album as a duo last year at the Old Siskiyou Barn. The self-titled release on Papillion Recordings will be available at the June 25 concert, and proceeds will benefit the Siskiyou Institute's Artists in Schools program.

The duo will present a blend of chamber music and American jazz that includes arrangements of spirituals, works by classical composers such as Samuel Barber and Johann Sebastian Bach, tunes by Duke Ellington and Thelonius Monk, pieces by contemporary composers such as Keith Jarrett and Sting and original compositions.

Grant and Matheny spice up their performances with personal stories, impromptu vocal riffs and playful camaraderie, drawing from a legacy that reaches back to vaudeville performers such as Williams and Walker and Noble Sissle and Eubie Blake, as well as the jazz duo of Louis Armstrong and Earl Hines.

Grant is an associate professor at Portland State University, where he directs the Leroy Vinnegar Jazz Institute. He is a graduate of the Eastman School of Music in Rochester, N.Y., and the University of Miami. Matheny has served as director of education for the San Francisco Jazz Festival. He is a graduate of the Berklee College of Music in Boston and was a protégé of flugelhorn legend Art Farmer.

Grant and Matheny also will hold a workshop at 11 a.m. Saturday at the Old Siskiyou Barn. The workshop's focus will be on the collaborative process of performing as a duo and the elements needed for creating an effective performance. The workshop is open to instrumentalists of all types. Admission to the workshop is $10, $5 for Siskiyou Institute members and free for students.

Tickets to Friday's show are $20, $15 for Siskiyou Institute members and $5 for students. Call 541-488-3869 or e-mail info@siskiyouinstitute.com for reservations and directions to the Old Siskiyou Barn.
