Blair, born Julieta Aylén Ordorica in Punta Alta, Buenos Aires province, was an Argentine singer-songwriter who first emerged in 2019 with the single "Al Final del Día", followed by early tracks such as "Sharigan", "Rocho" with BB Asul and "Empezar de Cero", rooted in Latin trap and the urban underground. Her buzz grew through 2020 as these singles accumulated significant streaming numbers and media attention, positioning Blair as a new voice from the Bahía Blanca area. In November 2022, she pivoted toward indie and alternative pop with her debut album Llorando en la Fiesta, produced by Dante Saulino and featuring songs like "Otra Noche en los '70", "Opuesto Complementario" and "Mi Suerte", which framed her introspective writing in a more guitar- and synth-driven sound. Over 2023 Blair expanded her live profile with slots at major Argentine festivals, headline shows in Buenos Aires venues such as Niceto and Vorterix, and a high-profile appearance connected to Taylor Swift’s The Eras Tour in River Plate Stadium, reinforcing her status on the national circuit. In 2024 she continued releasing singles, including "La Paz de los Cementerios", while working on a second full-length. On February 25, 2025 she released "Todo lo que Tengo", presented as the first single of a new era and later included on her sophomore album BAR SCORPIOS, issued on April 23, 2025 by Sony Music Argentina with collaborations from Dillom on "Carne Viva", Mariana Enriquez on "Pecados Brutos" and Santiago Motorizado on "Hombre Roto", marking a darker, more rock-leaning evolution for Blair’s sound.
