Bach's six Cello Suites are profound works. Dance-like but abstract, orderly but deeply emotional, and polyphonic even when only one line being is played at a time. This particular movement is the Sarabande (a slow and stately dance) from the second, rather melancholy suite. It is moody and melancholy, almost funereal, but yet occasionally buoyed by a certain... contentment and balance. I love this particularly recording; Peter Wispelwey is playing on an older instrument that's tuned about a half-step lower. Earthy, sonorous, dark, and deep.
