Antoine Berthiaume is a Canadian composer and performer, proficient in guitar and banjo, born in Montréal, Québec, in 1977. Initially aspiring to become an architect or cartoonist, he demonstrated artistic talent from a young age. However, his interest in comic books waned as he found greater enjoyment in music and collaboration, leading him to pick up the guitar at age 15. He formed his first band with Alexis Trepanier, who later became a prominent web designer. Influenced by renowned guitarists like David Gilmour, Jimmy Page, and Andy Summers, Berthiaume quickly sought new musical horizons. By age 17, he shifted from blues and rock to jazz, studying under Marc-André Laporte and Éric St-Laurent in Montréal, followed by a two-year program at Cégep Saint-Laurent with Benoît Charest specializing in jazz guitar.
Berthiaume honed his skills at the Montréal jazz club l’Air du Temps, where he played with some of the city's finest musicians. He spent a year as the host of the house band alongside drummer Magella Cormier and bassist François Turgeon, delving into standard jazz and free music.
After studying under Neil Smolar in Montréal, Berthiaume moved to Toronto for lessons with Lorne Lofsky. However, he found Toronto unsatisfactory and returned to Montréal before heading to New York to study with saxophonist Dave Binney. In New York, he enjoyed the company of friends from the ballet world, including dancers Ellen Bar and Sean Suozzi, who continue to inspire his music.
A pivotal moment in Berthiaume's musical journey occurred during a visit to the legendary improviser Derek Bailey's home in London in 2002. After a meaningful conversation about life and music, he returned for a recording session that resulted in music released on Ambiances Magnétiques and Incus Records, featuring Bailey and Fred Frith.
Following a period of private study, Berthiaume decided to return to academia. The dean of Université de Montréal recognized his unconventional trajectory and allowed him to bypass a Bachelor’s degree to pursue a Master's in contemporary composition. His three years at the university, which included a semester at Mills College in California under Fred Frith and Joëlle Léandre, significantly reshaped his understanding of music, introducing him to avant-garde concepts. He was particularly influenced by professors Michel Longtin and Jose Evangelista.
His time at Mills College proved to be a highlight of his career, where he connected with pianist Quentin SirJacq and sound engineer Norman Teale, leading to the album Leaves and Snows, also released on Ambiances Magnétiques. Engaging with talented improvisers like MaryClare Brzytwa and Teresa Wong challenged his artistic development. After completing his Master's in 2005, Berthiaume returned to New York for six months, studying guitar with Mordy Ferber and living with inspiring artist Molly Culver before permanently relocating back to Montréal. Although he considered staying in New York, he opted against it due to the complexities of obtaining a Green Card.
In recent years, Berthiaume has participated in the Montréal International Jazz Festival (FIJM) and continues to perform locally with various improvisers and his band, Rodeoscopique. He also toured Japan, collaborating with Yuki Saga, Haco, and several local musicians, and recorded an album in Kobe with guitarist Takumi Seino, released on VOS Records in Japan.
In 2006, Berthiaume's performance schedule includes the FIMAV (Festival International de Musiques Actuelles de Victoriaville) with SirJacq and Teale in May, a concert in the Seychelles with Allan Camille in August, and appearances in Paris and Amsterdam with SirJacq and Joëlle Léandre in March, alongside ongoing performances in Montréal.
A forthcoming jazz album featuring Berthiaume's compositions, alongside musicians Michel Donato and Pierre Tanguay—his sole mentor—is in the works. Additionally, he is set to be included in a book by Ralph Gibson titled State of the Axe, which highlights avant-garde guitarists and features contributions from notable musicians such as Derek Bailey, Andy Summers, Jim Hall, Bill Frisell, and Marc Ribot.
Berthiaume has received support from the Canada Council for the Arts (four grants), the Conseil des arts et des lettres du Québec (three grants), and the Fondation du Maire de Montréal pour la jeunesse.
