Duo Karuna with Jessica Kaiser (Guitar) & Johanna Rupper (violin) perform Fratres by Arvo Pärt (b.1935). This comes via Open Strings Berlin and their absolutely fantastic Youtube Channel. Great playing here and such a beautiful expansive sense of space and pacing.
The piece has gone through so many permutations and this arrangement only contributes to that tradition. via wiki: “Fratres (Brothers) is a composition by the Estonian composer Arvo Pärt exemplifying his tintinnabuli style of composition. It is three-part music, written in 1977, without fixed instrumentation and has been described as a “mesmerizing set of variations on a six-bar theme combining frantic activity and sublime stillness that encapsulates Pärt’s observation that ‘the instant and eternity are struggling within us’.”
Also see JIJI playing Fratres (arr. and electronics by JIJI) for another example.
