Airs Monday, October 29 at 11:00 a.m. This week on Summer Stages it's back-to-back Bach. First a traditional interpretation when cellist Jonathan Cohen tackles some of his music for viola da gamba and then mandolinist Chris Thile puts aside bluegrass for Bach! We'll hear Bach's Solo Cello Suite No.1 in Major and Bach's Viola da Gamba Sonata No.1 in G Major. Also on the program, Beethoven's Rondo in C, Op.51 No.1 and his Cello Sonata No.2 in G Minor op.5 with Jonathan Cohen, Cello and Kristian Bezuidenhout, harpsichord and fortepiano. Back to Bach with his Violin Sonata in G minor featuring Chris Thile on mandolin and we'll close with Mendelssohn's String Quintet No.2 in B-flat, Op.87.
