Sadie Dupuis

Dupuis began playing music as a child through choirs and piano playing. She joined a professional choir in middle school and toured internationally with it through high school. She learned to play guitar at the age of 13.[4] When she was 14, she spent one year studying at Kent School, a private co-educational college preparatory school in Kent, Connecticut.[5] She is a graduate of Shepaug Valley High School in Washington, Connecticut.[1] She is also an alumna of Buck's Rock, an educational arts camp where she was both a student and an instructor of music, which later inspired Speedy Ortiz to fundraise for Girls Rock Camp.[6]

Dupuis attended the Massachusetts Institute of Technology (MIT) for two years. She pursued dual degrees in mathematics and music before becoming interested in the school newspaper and eschewing mathematics in favor of writing. After leaving MIT, she completed her schooling at Barnard College with a concentration on poetry. Before becoming a full-time musician, she worked as a freelance writer as well as teaching writing and getting an MFA in poetry at University of Massachusetts Amherst.[7]

During 2011, Dupuis played in "the all-female Pavement cover band" Babement.[8] It was formed with Cindy Lou Gooden, of Very Fresh,[9] but they only performed a "couple shows."[10] Dupuis released two albums with her band Quilty, both released on Cooling Pie Records. The band split up in 2012 while Dupuis pursued Speedy Ortiz. Also during 2012, Dupuis' side project Dark Warble released an EP entitled Moon is Trouble. Dupuis wrote her first Speedy Ortiz song, "Ka-Prow", while teaching song writing at Buck's Rock summer camp in 2011.[11] Speedy Ortiz released its first EP, Cop Kicker, in 2011. Dupuis quit her job and became a full-time musician while preparing for the release of Speedy Ortiz's second album, Foil Deer.[12] She has also featured in numerous tracks by Ovlov in which she provides backing vocals.[13] In January 2016, Dupuis, under the name Sad13, worked with alternative Hip Hop artist Lizzo and recorded the song "Basement Queens".[14] In November 2016 she released the album Slugger under the same name.[3] In November 2018, she released her first book of poetry, Mouthgard.

Dupuis is a vegan [15] and as of 2018 has eaten a vegan diet for more than thirteen years.[16]

Dupuis' late father, William D. Kornreich,[17] worked as an A&R at ZE Records, Buddah Records, and United Artists,[18] and helped found the Rock and Roll Hall of Fame.[19]
