Cesar Rosas, born on September 26, 1954, in Hermosillo, Mexico, is a renowned singer, songwriter, and guitarist best known for his work with the band Los Lobos. He is also a member of the Latin supergroup Los Super Seven. Rosas is easily recognizable by his trademark black sunglasses, goatee, and slicked-back black hair.

Los Lobos' music is a dynamic blend of rock, Tex-Mex, country, folk, R&B, blues, and traditional Spanish and Mexican music. The band gained widespread acclaim with their major label debut "How Will the Wolf Survive?" in 1984 and achieved a global hit with their rendition of "La Bamba" in 1987.

In addition to his work with Los Lobos, Rosas has been active as a session musician and sideman over the years. He released a solo album titled "Soul Disguise" in 1999 and toured following its release. Rosas continues to perform live, including select dates on the 2025 Experience Hendrix Tour.

Cesar Rosas' contributions to music extend beyond his performances; his work captures the essence of Chicano rock, Tex-Mex, and blues-rock, making him a significant figure in these genres.
