Brooklyn guitarist and composer Mary Halvorson returns with About Ghosts, packed with eight new compositions performed by her sextet, Amaryllis. The group includes Patricia Brennan on vibraphone, Nick Dunston on bass, Tomas Fujiwara on drums, Jacob Garchik on trombone and Adam O'Farrill on trumpet, with guest saxophonists Immanuel Wilkins and Brian Settles. Produced by John Dieterich, the album blends layered horn arrangements and subtle synth textures, including a Pocket Piano gifted by a childhood friend. The record continues to explore plenty of evocative improvisational terrain that builds on her already acclaimed discography with layered melodies, weird non-guitar sounds and plenty of free-spirited exploration.
