There’s a considerable discography of Theo Loevendie out there, but the only composition of his that I’ve reviewed so far is the not entirely significant pieces for two pianos eight-hands “For Jan, Piet and Klaas” from 1979, played by the Dutch Pianist’s Quartet on “Works for two pianos eight hands”, Attacca Babel 9481 (1994), with compositions of Robert Nasveld, Ton Brunyèl Ravel, François-Bernard Mâche and Graham Fitkin.
