El Tri is a legendary Mexican rock and blues-rock band led by Álex Lora, recognized as one of the most important and long-running acts in Mexican rock. Emerging from the legacy of Three Souls in My Mind, the band is known for socially direct lyrics, raspy vocals, and songs including “Triste Canción,” “Pobre Soñador,” “Las Piedras Rodantes,” “ADO,” and “Metro Balderas.” El Tri remains a foundational name for rock en español and Mexican rock concert listings.
