Information for Nils Frahm at Barbican Centre, West End (Concert). Berlin-based contemporary composer Nils Frahm has built a steady reputation for his intimate, poignant piano recordings, yet they so far only showed a fragment of what to expect from a Nils Frahm concert. Frahm's heart lies in improvisation, in the magic of a moment where, inspired by the space and the audience, his fingers can create new compositions loosely based around his familiar melodies.
