Mary Halvorson’s Reverse Blue

Thanks to constant work, the guitarist’s ideas are boundless these days. She’s built this quartet around reed player Chris Speed, bassist Eivind Opsvik and drummer Tomas Fujiwara to enjoy textural gambits and counterpoint experiments. Abstraction is the welcome mat of their new album on the Relative Pitch label, but poignant moments and defined landscapes are always popping up.
