The Guardian said Halvorson’s Nonesuch Records debut, the 2022 double release Amaryllis / Belladonna “shows how far this singleminded original has come, and affords a glimpse of how far she may go. Both sessions confirm how years of jaggedly lyrical solo and ensemble improvising and a quirkily subversive affection for mainstream music have now nurtured a composer of unpredictable but warmly expressive character… These are new landmarks in Halvorson’s already inimitable discography.” Pitchfork said, “Amaryllis and Belladonna are distinct statements; one could hear either album on its own without a sense that something is missing. But they are most powerful when taken together, like a landscape and its reflection in rippling water.” Halvorson has released a series of critically acclaimed albums, from Dragon’s Head (2008), her trio debut featuring bassist John Hébert and drummer Ches Smith, expanding to a quintet with trumpeter Jonathan Finlayson and alto saxophonist Jon Irabagon on Saturn Sings (2010) and Bending Bridges (2012), a septet with tenor saxophonist Ingrid Laubrock and trombonist Jacob Garchik on Illusionary Sea (2014), and finally an octet with pedal steel guitarist Susan Alcorn on Away With You (2016). She also released the solo recording Meltframe (2015), debuted Code Girl (2018) , a new ensemble featuring vocalist Amirtha Kidambi, trumpeter Adam O’Farrill, saxophonist and vocalist María Grand, bassist Michael Formanek, and drummer Tomas Fujiwara.
