Bach Week is devoted to the performance and exploration of the music of Johann Sebastian Bach. Events range from chamber music performed on period instruments to the collaborative performance of large vocal and instrumental works by students and professionals. Free demonstrations and lectures provide additional context for these performances.

In 2011, Thomas Davies and David Arrivée established Bach in the Mission as an annual, collaborative concert that would give Cal Poly student musicians the opportunity to rehearse and perform with faculty and local professionals the vocal and instrumental music of Bach. The two had long wanted to apply their shared interest and experience to such an educational project, and since its inception, Bach in the Mission has grown each year. Join Arrivée and new co-director Scott Glysson Jan. 16 for Inside Bach Week, an in-depth look at the repertoire of Bach Week.

The guest artists this year will be Clifton Swanson, and the musicians of Mensa Sonora California.

At 11 a.m. on Jan. 18, Mensa Sonora California musicians David Wilson, Anthony Martin, John Dornenburg and Charles Sherman will present a master class in which they will coach Cal Poly students in chamber music and solo repertoire, with a focus on historically informed performance.

At 7:30 p.m. on Jan. 18, Swanson will give a presentation titled "Student and Teacher."

On Jan. 19, Mensa Sonora California will perform a chamber concert titled "Bach and His Students" in Mission San Luis Obispo on period instruments and will also perform on the Jan. 20 concert.

The Saturday cornerstone concert Bach in the Mission VIII is complemented by the events earlier in the week.
