Ethel Bartlett and Rae Robertson both studied with Tobias Matthay in the 1910s. They established a two-piano duo that quickly became the first such team to achieve truly international fame. From the 1930s they based themselves in the USA where they gave important American premieres of works by Poulenc and Stravinsky. They made first recordings of much of the standard two-piano repertoire and also inspired many new works and arrangements. Given their significance, it is surprising that this important legacy has been completely neglected since the 1950s and this issue is the first CD release ever devoted to their recordings.
