Searingly passionate, powerfully intense, completely in control of the technical and rhythmic difficulties, and understanding of the musical and expressive complexities of the work, while always beautiful of sound, it seems to me to be the best performance of the cello sonata, either live or on recording, that I have experienced.
John Rodney Lister, Cambridge Journals/Tempo

– Played with charismatic brilliance. Johannes Martens and Joachim Kwetzinsky revel in fine detail without ever losing a sense of its overarching shape.
Catherine Nelson, The Strad

– The most useful CD to have come out of the Carter centenary.
Andrew Clark, chief classical music critic, Financial Times

– A top rank and highly vivid way in for anyone aspiring to get Carter. Anyone seeking a ”way in” could not hope for better.
Richard Whitehouse, Gramophone

Martens and Kwetzinsky play the Cello Sonata with great accuracy. One really feels the relations between the rhythms, and there is great clarity and enjoyment in their interpretation. This is a rather special release in that way.
D. Moore, American Record Guide

Martens/Kwetzinsky ist überragend und in vielem noch brillanter und frischer als die Interpretation der von Carter bevorzugten Altmeister Greenhouse/Webster.
Toni Hildebrandt,

– Gripende tolket av Martens og Kwetzinsky.
Astrid Kvalbein, Aftenposten

– Der er arvtagere etter Liv Glaser, Einar Steen-Nøkleberg, Aage Kvalbein og Truls Mørk. Konserten onsdag kveld var slik sett en slags «forskudd på arv».
Håkon Sødal, Lindesnes

– Marcus Paus sin splitter nye "Sonate for cello og klaver" viser en komponist som utvilsomt har noe på hjertet.(....)De glimrende utøverne Johannes Martens og Joachim Kjelsaas Kwetzinsky var også avgjørende bidragsytere til det gode resultatet.
