“The concert by the duo of Colin Carr (violoncello) and Thomas Sauer (piano) proved very revealing in contrasting the eloquence of the mid-twenty-year-old [Beethoven] with the laconic severity of the seasoned master. Especially since Carr and Sauer performed the early pieces quite other than casually, they rather took them wonderfully seriously. Only this artistically serious standpoint made possible a clear insight and an appropriate comparison of both styles of a single composer. Carr’s slender, focused cello tone, [and] Sauer’s highly resolved, structurally clear piano playing provided for optimal transparency. Both the austere character of the C-major Sonata and the songlike compactness of expression of its sister-work in D major with its fugal finale stood out.”
