Query: If You're Buying Your First Los Lobos CD

This is the one to buy. Two cd set starts off with more latin based music on the first disc and slowly turns more to rock & roll including a great cover of Marvin Gaye's "What's Going On?" These guys are all excellent musicians who are greatly underappreciated by most of the people I know--"La Bamba" was both a blessing and a for them as far as I'm concerned. These guys play an eclectic blend of music and can play anything so well. See them live and you'll know what I'm talking about.
