If anyone knows where to find the blues, it’s Taj. A brilliant artist with a musicologist’s mind, he has pursued and elevated the roots of beloved sounds with boundless devotion and skill. Then, as he traced origins to the American South, the Caribbean, Africa, and elsewhere, he created entirely new sounds, over and over again. As a result, he’s not only a god to rock-and-roll icons such as Eric Clapton and the Rolling Stones, but also a hero to ambitious artists toiling in obscurity who are determined to combine sounds that have heretofore been ostracized from one another. No one is as simultaneously traditional and avant-garde.

The journey of Los Lobos began in 1973, 50 years ago this year, when David Hidalgo (vocals, guitar, and pretty much anything with strings), Louie Perez (drums, vocals, guitar), Cesar Rosas (vocals, guitar), and Conrad Lozano (bass, vocals, guitarrón) earned their stripes playing revved-up versions of Mexican folk music in restaurants and at parties. The band evolved in the 1980s as it tapped into L.A.’s burgeoning punk and college rock scenes. They were soon sharing bills with bands like the Circle Jerks, Public Image Ltd. and the Blasters, whose saxophonist, Steve Berlin, would eventually leave the group to join Los Lobos in 1984.
