Sparta is an American rock band from El Paso, Texas, formed in 2001. Founding members Jim Ward (vocalist/guitarist) and Tony Hajjar (drummer) are also members of post-hardcore group At the Drive-In. Keeley Davis (guitarist) is the former frontman of Engine Down.
Keeley Davis is from El Paso, Texas.
There is no mention of where Keeley Davis is from, so he could be from El Paso or he might not be.  Thus, the statement is neither definitely correct nor definitely incorrect.  The system seems to think that all the members of the band are from El Paso because the band was formed there, even though that's not necessarily true, and it's especially not necessarily true for Keeley Davis, who isn't a founding member of the band.
