Cameron Dupuy was born and raised in Kenner, Louisiana, a suburb of New Orleans, the son of Cajun musician Michael Dupuy. His father brought him to gigs from an early age, where Cameron would strum a guitar, bang on spoons, or grab whatever instrument he could reach. He started playing guitar seriously around age eight, but everything changed during the Hurricane Katrina evacuation in 2005, when the Dupuy family sheltered with a family friend in Lafayette. On the last day of the evacuation, Cameron talked his host into letting him play an accordion that had been used to record a Grammy-winning album by Cajun legend Jimmy Breaux — and he was instantly hooked.
Back home, Cameron picked up his father's long-unused accordion and, according to Michael Dupuy, "hasn't put it down since." By age 11 he was studying the repertoire of Cajun masters Marc Savoy, Aldus Roger, and Belton Richard, and a breakout performance at The Liberty Theatre in April 2010 earned a standing ovation and an invitation from Cajun music scholar Dr. Barry Ancelet to play Festival Acadiens et Creoles. As a teenager, Cameron joined the youth ensemble Huval, Dupuy & Fuselier, which released an album on the storied Swallow Records label and toured Canada; that group eventually evolved into Cameron Dupuy & the Cajun Troubadours.
The band built its following the traditional way, with twice-weekly residencies at the Tropical Isle Bayou Club on Bourbon Street and regular sets in Concourse C of Louis Armstrong New Orleans International Airport. Their self-titled debut album, released on Camo Records in March 2020, featured 15 tracks — more than half of them instrumentals — and earned a Grammy nomination for Best Regional Roots Music Album that November. Cameron, now an eight-time Cajun accordion contest winner, continues to perform with his father and fiddler Beau Thomas at festivals across Louisiana, including a regular slot at Jazz Fest.
