Arvo Pärt: Tabula Rasa (Gidon Kremer, Keith Jarrett, Staatsorchester Stuttgart, ECM 1984)

This 1984 ECM album brought Pärt's tintinnabuli technique to a wide audience: one voice sounding the notes of a central triad, another stepping along a scale. In the title work, Gidon Kremer and Tatjana Grindenko play with hushed intensity, and the slowly shifting intervals and silences turn quiet repetition into something deeply spiritual. Choose it for the stillest, most meditative entry here.
