Lara Downes thinks we have reached the right moment for unfamiliar music presented in a new way.

Downes, the founder and curator of Rising Sun Music, has spent decades finding and preserving the music of Black composers from several continents and many centuries. The pianist has been adding to her already significant discography with monthly digital releases of four or five pieces from this repertoire since February, and the first full album, New Day Begun, appeared in July. Across the recordings, she has collaborated with musicians ranging from violinist Regina Carter and violist Jordan Bak to soprano Nicole Cabell and bass-baritone Davóne Tines to the PUBLIQuartet.
