Mary Halvorson

Mary Halvorson operates as a guitarist, bandleader, and composer whose approach consistently defies conventional genre boundaries through a recognizable instrumental voice and an aesthetic that shifts from one recording to the next. Her music fuses strong jazz foundations with indie rock, folk, and further traditions. She launched her recording activity in 2002 as a participant in the jazz-rock quartet Friendly Bears. Recognition as a leader followed with the 2005 duo release Prairies alongside violinist Jessica Pavone. Dragon's Head, a trio project, appeared in 2008. The quintet debut Saturn Sings arrived in 2010, succeeded in 2012 by Bending Bridges, while the septet received its showcase on 2013's Illusionary Sea. Thumbscrew originated in 2014 when she joined forces with Tomas Fujiwara and Michael Formanek. The solo guitar album Meltframe surfaced the next year. Code Girl, issued in 2018 as a double-length set, ranked among that year's most celebrated jazz releases and reinforced her receipt of a MacArthur Foundation Grant. Artlessly Falling came afterward. Following the 2021 duo album Searching for the Disappeared Hour with pianist Sylvie Courvoisier, she simultaneously released two pandemic-era projects in 2022: Belladonna for sextet and Amaryllis for solo guitar with the Mivos Quartet string ensemble. Her sextet delivered Cloudward in 2024, and Tzadik put out Halvorson's Bagatelles, Vol. 1 in February 2025.

Born in Brookline, Massachusetts, in 1980, Halvorson began musical study on violin before turning to guitar upon encountering Jimi Hendrix. Her initial aim centered on rock performance. Because her earliest instructor was a jazz musician, her focus shifted. She continues to claim affiliation with "jazz" while harboring reservations, an outlook consistent with a style that operates beyond genre lines. After completing a B.S. in Music at Wesleyan University, she relocated to Brooklyn, New York, in 2002 and pursued further study at the New School of Jazz & Contemporary Music. There she linked up with a notable roster of veteran musicians rooted in the contemporary new-music lineage, among them Anthony Braxton, who incorporated her into multiple ensembles. Additional significant collaborators encompass Jessica Pavone, Taylor Ho Bynum, Tim Berne, Trevor Dunn, Assif Tsahar, Matana Roberts, Ted Reichman, Stephen Haynes, Curtis Hasselbring, Jason Moran, Tony Malaby, Nicole Mitchell, Elliott Sharp, and John Tchicai. Beyond performance, she has instructed at the New School and led workshops for the School for Improvised Music.

Recordings under her leadership include the UgExplode duet Opulence with San Francisco drummer Weasel Walter and the 2008 Skycap title Calling All Portraits; Thin Air on Thirsty Ear and the widely praised Dragon's Head on Firehouse 12, featuring bassist John Herbert and drummer Ches Smith, both appeared in 2009. That year also saw the release of Crackleknob by Halvorson and her ensemble. Return to the duo format with violinist Jessica Pavone yielded 2011's Departure of Reason. In the following year she issued the quintet recording Bending Bridges and united with trumpeter Peter Evans and drummer Walter for the trio project Mechanical Malfunction.

Remaining highly active, Halvorson issued several projects across subsequent years, among them the 2013 septet album Illusionary Sea, the 2014 self-titled debut of the Thumbscrew trio with bassist Michael Formanek and drummer Tomas Fujiwara, and the 2015 solo guitar effort Meltframe. That same year she joined drummer Tom Rainey and saxophonist Ingrid Laubrock for the trio album Hotel Grief. Thumbscrew's second album, Convallaria, arrived in 2016 with Formanek and Fujiwara, while the octet recording Away with You also appeared that year. Err Guitar, released in 2017, placed her in an experimental guitar trio alongside Marc Ribot and Elliott Sharp.

During this period Halvorson assembled a fresh ensemble for an upcoming recording and performance venture that included her Thumbscrew colleagues Formanek and Fujiwara plus trumpeter Ambrose Akinmusire and vocalist Amirtha Kidambi of the New York improv collective Elder Ones. Having drawn inspiration from Robert Wyatt, Elliott Smith, and American postmodern poets, she had composed lyrics over an extended span and had previously presented them within an avant-folk duo with Jessica Pavone and in the band People with Kyle Foster and Kevin Shea.

Code Girl, a double-length endeavor, advanced further. Musically it traversed the array of genres already explored in her work as composer and arranger, yet integrated them into intricate, labyrinthine songs that placed those compositional abilities beside the improvisational strengths of her band. Firehouse 12 released the album in spring 2018 as the quintet toured Europe with Adam O'Farrill substituting for Akinmusire. The year yielded three additional duo recordings: The Maid with the Flaxen Hair: A Tribute to Johnny Smith with guitarist Bill Frisell on Tzadik, Seed Triangular with flutist Robbie Lee on New Amsterdam, and Traversing Orbits with guitarist Joe Morris on Rogue Art. Thumbscrew simultaneously issued two albums, Theirs, a set of covers, and Ours, consisting of originals. She also supplied a version of "With a Little Help from My Friends" to Verve's Sgt. Pepper's Lonely Hearts Club Band tribute compilation A Day in the Life: Impressions of Pepper and appeared on releases by Maria Grand (Magdalena on Biophilia) and Ingrid Laubrock (Contemporary Chaos Practices on Intakt).

Halvorson received a MacArthur Foundation Genius Grant in 2019 before reaching age 40. She toured extensively with Code Girl and as a member of steel guitar master Susan Alcorn's quintet for much of the year. In January and February 2020, Thumbscrew released their fourth long-player, The Anthony Braxton Project, devoted entirely to works by its namesake. Issued in July, it preceded the October appearance of Artlessly Falling, the second Code Girl album. With O'Farrill now a permanent member, the group expanded to a sextet upon the addition of saxophonist and vocalist Maria Grand. Co-produced by the guitarist, Nick Lloyd, and David Breskin, the album balanced Halvorson's songs and poems. Robert Wyatt guested on three of its eight tracks. In November, Relative Pitch issued Pedernal by the Susan Alcorn Quintet, featuring the pedal-steel improviser and Halvorson alongside violinist Mark Feldman, bassist Michael Formanek, and drummer Ryan Sawyer.

Halvorson and pianist Sylvie Courvoisier released the live duo album Searching for the Disappeared Hour in 2021. Her quartet also contributed the first of four discs in John Zorn's Bagatelle: Box 1 series, containing performances drawn from the composer's most recent book of compositions at that time. In May 2022 she issued two albums concurrently on Nonesuch for her label debut. Amaryllis was scored for jazz sextet, while the companion recording Belladonna presented her initial compositions for solo guitar and the Mivos String Quartet.

By 2023 the Amaryllis sextet had become a fully operational performing and touring unit. The ensemble released the full-length Cloudward, containing eight Halvorson compositions, on Nonesuch in January 2024. In February 2025, Tzadik reissued the Halvorson quartet's contribution from the Bagatelles box as the standalone title Bagatelles, Vol. 1.
