Antonin Dvořák's Cello Concerto in B minor, Op. 104 is a perennial audience favorite, and many cellists play and even record it with conductors with whom they may only have a passing acquaintance. The work is relatively forgiving of such treatment, with melodies, that once heard, reside in the mind forever and need only to be refreshed. However, there's room for more progressive treatments of the work, and this one is an example, with the young cellist Kian Soltani joining Daniel Barenboim and his well-drilled Staatskapelle Berlin. Soltani and Barenboim have worked together consistently; Soltani was the principal cellist in Barenboim's West-Eastern Divan Orchestra in the Middle East.
