Toronto keyboardist R. Grunwald has played on sessions for hundreds of musicians, and has served as bandleader for jazz/pop chanteuse Jill Barber and country/folk songwriter Donovan Woods for the better part of a decade. Now he’s ready to step onto the public stage with his own music—alone. Oma is an evocative and deeply personal solo piano record, inspired in part by the life story of his 96-year-old grandmother, a Holocaust survivor and pianist. Drawing from Erik Satie, Nils Frahm and others, Grunwald refers to his intensely melodic compositions as “extended minimalism.”  You’ve heard other solo piano records this year, but none like this one.
