People like to pigeon-hole pianists. There are, we are routinely told, the barnstormers – romantic pianists who throw the entire force of the heart and soul into their playing – and then there is the more analytical school – those who play by intellect, everything meticulously thought out and delicately weighted. By and large it's piffle, of course; few pianists would admit to excluding head or heart in their playing and great interpretations are forged through a combination of the two, and more besides. But German-born Burkard Schliessmann rejects such divisions more than most.
