This Deluxe vinyl 2LP-set compiles Mary Halvorson's two new releases Belladonna and Amaryllis. The two suites, which Halvorson describes as "modular and interlocking," were performed at Brooklyn's Roulette last fall and were produced and mixed by John Dieterich (Deerhoof). Amaryllis is a six-song suite performed by a newly formed sextet of master improvisers, including Halvorson, Patricia Brennan (vibraphone), Nick Dunston (bass), Tomas Fujiwara (drums), Jacob Garchik (trombone), and Adam O'Farrill (trumpet). The Mivos string quartet joins for three of the songs, making this the largest ensemble for which Halvorson has written to date. The suite showcases Halvorson's many musical influences from jazz, experimental, new music, and beyond. Belladonna is a set of five compositions written for Halvorson on guitar plus The Mivos Quartet: Olivia De Prato (violin), Maya Bennardo (violin), Victor Lowrie Tafoya (viola), and Tyler J. Borden (cello). It is Halvorson's first time writing for a string quartet. Mivos' parts are through-composed and augmented by Halvorson's guitar improvisations.
