According to Allmusic's Stephen Thomas Erlewine, "Los Super Seven isn't a band, per se – it's a collective, organized by manager Dan Goodman, who comes up with a concept for each of the group's albums and assembles a band to fit.
"[1] The collective has released three albums to date, with wildly varying personnel.
Only Ruben Ramos and Rick Trevino are featured on all three releases.
Their musical style has changed with each incarnation, blending sounds from Tejano, mariachi, Cuban, Afro-Peruvian, Brazilian, blues, rhythm and blues, country, jazz and rock.
The personnel included the members of Texas Tornados, Los Lobos, Calexico, Ozomatli, and others.
