Los Ángeles Azules is a Mexican musical group formed in Mexico City in the late 1970s by siblings from the Mejía Avante family, including Elías, José, Jorge, Alfredo, Cristina, and Guadalupe. Originating from the working-class neighborhood of San Lucas in Iztapalapa, the band started playing cumbia sonidera at local events like weddings and quinceañeras to support their family financially. Their first album, Ritmo, Alegría y Sabor, was released in 1982, followed by a major hit with Cómo Te Voy a Olvidar in 1997, which achieved significant popularity. The group specializes in cumbia, onda grupera, and later innovations like cumbia sinfónica, collaborating with artists such as Lila Downs, Carla Morrison, Ximena Sariñana, and Natalia Lafourcade on albums including Cómo Te Voy a Olvidar Edición de Súper Lujo (2014) and De Plaza en Plaza (2016). They received a Billboard Latin Music Awards nomination in 2001 and performed at Coachella in 2018, the first traditional cumbia group to do so. Known for energetic live shows that connect audiences through danceable rhythms, their performances draw crowds at festivals and parties worldwide.
