On Classical King’s “Northwest Focus Live” with Sean MacLean, cellist Efe Baltacigil and percussionist Mari Yoshinaga spice up two JS Bach pieces that are often performed on cello alone. Bach's cello suites (BWV 1007-1012) were written between 1717 and 1720 and remained fairly unknown until cellist Pablo Casals popularized them in the 20th century. These suites are mandatory for any aspiring cellist, Efe and Mari add a twist by bringing in a rhythm section.
