On this EP of six tracks, brothers and pianists Lucas and Arthur Jussen explore repertoire that was originally based on a sacred aria or chorale melody. CANTUS includes Anderson and Roe’s two-piano arrangement of “Aus Liebe will mein Heiland sterben” from Bach’s St. Matthew Passion, and Reinhard Febel’s four-hand arrangement of Bach’s setting of the chorale “Erbarm dich mein, o Herre Gott.” The brothers also play three of Johannes Brahms’s Chorale Preludes, Op. 122 arranged for piano four-hands by Eusebius Mandyczewski. The EP is rounded out by the piano duo version of Arvo Pärt’s Pari Intervallo.
