Kara-Lis Coverdale’s beautiful “Grafts” starts with sounds that are like soft things falling a long way. Phased organ exhalations. Instruments suspiring in cushy environs, reacting to each other, provoking further action. But that’s not the whole story. It’s a protean piece, all 20+ minutes keep moving, dancing off-balance—later in the piece, notes from a piano flutter in a stiff wind. Still later: prepared pitter patter and steam releases. Coverdale shares sound space with folks like Ellen Arkbro and Nils Frahm, composers who like to experiment with soundcraft and form. “Grafts” is incredible, can’t recommend this one highly enough.
