Kali Malone composes post-minimalist pieces implementing specific tuning systems, including works for choirs and chamber ensembles as well as acoustic and electronic instruments. She is best known for her pipe organ compositions, including the acclaimed 2019 release The Sacrificial Code, though she has also produced electro-acoustic drone releases such as 2022's Living Torch and has additionally participated in projects ranging from noise to shoegaze. She collaborated with Stephen O'Malley and Lucy Railton for 2023's Does Spring Hide Its Joy.

Kali Malone was born in Colorado in 1994 and later moved to Stockholm in order to study electro-acoustic composition in 2012. She participated in an ensemble called Golden Offence Orchestra and conducted an arrangement of the Pauline Oliveros piece "To Valerie Solanas and Marilyn Monroe in recognition to their desperation." She also played in an experimental audiovisual group named Hästköttskandalen, along with musicians such as Ellen Arkbro and Maria W. Horn, and she was the leader of the shoegaze group Swap Babies. Malone and Horn co-founded the label and concert series XKatedral in 2016. Malone released several limited cassettes of her music, including pieces with Arkbro and Caterina Barbieri, and her first full-length LP, Velocity of Sleep, appeared in 2017. Her EP Organ Dirges 2016-2017 was released by Ascetic House the following year, and Cast of Mind, an LP of horn-based drones, appeared on Hollow Ground. Malone collaborated with Acronym on an ambient techno EP titled The Torrid Eye, which was released by Stilla Ton at the beginning of 2019. The Sacrificial Code, a nearly two-hour set of pipe organ compositions, was released by iDEAL Recordings and quickly earned praise from critics and listeners. Malone released Studies for Organ, a tape of rehearsals, in 2020 and appeared on former Coil member Drew McDowall's fourth solo album, Agalma. She contributed a piece to Important Records' 2021 release The Harmonic Series Vol. 2, along with other composers such as Tashi Wada and Catherine Lamb. Living Torch, commissioned by electro-acoustic music studio GRM and released by their Portraits GRM imprint, appeared in 2022. Malone recorded Does Spring Hide Its Joy, a set of three hour-long drones, with guitarist Stephen O'Malley and cellist Lucy Railton. The album was released by O'Malley's Ideologic Organ in 2023. ~ Paul Simpson

Lucy Railton is a British cellist, composer, and curator whose work pushes the edge of electro-acoustic composition. After graduating from the Royal Academy of Music, appearing on dozens of recordings, and performing at numerous contemporary music festivals and venues, she made her solo debut with the 2018 full-length Paradise 94, a jarring mixture of intensely amplified cello and industrial noise textures.

Railton was trained at the New England Conservatory in Boston as well as the Royal Academy of Music in London, where she graduated in 2008. During the same year, she established the new music series Kammer Klang, and she later co-founded the London Contemporary Music Festival. Her programs present performances of canonical works as well as pieces by emerging and lesser-known composers. Railton has played on recordings by numerous jazz, folk, electronic, and indie rock artists, including Bat for Lashes, Orbital, Bonobo, and Jamie Cullum. She has performed or recorded extensively with Thomas Strønen, Russell Haswell, Sofia Jernberg, and others.

In 2018, Modern Love released Railton's first album, Paradise 94, which included collaborations with artists such as Beatrice Dillon and Kit Downes. She collaborated with Peter Zinovieff, co-founder of the EMS Synthesizer company, on RFG Inventions for Cello and Computer, which was released by PAN in February 2020. Three months later, Railton's improvisational Lament in Three Parts was issued by Cafe Oto's digital label TakuRoku. Her composition Forma was released by Portraits GRM (a collaboration between Austrian experimental label Editions Mego and French electro-acoustic institution INA GRM) as the first side of a split LP with Baltimore-based experimental musician Max Eilbacher. Railton's 2010 performance of Louange à l'Éternité de Jésus by Oliver Messiaen was issued by Modern Love as a benefit recording, with proceeds split between the UN Refugee Agency COVID-19 Appeal and the Grenfell Foundation. ~ Paul Simpson
