Excellent instance and example of nothing but first-rate work in Los Lobos, tostadosunidos! By the way, I learned of them in a great manner: I went to see The Plimsouls at a little dive on Ventura Blvd. in Studio City named The Garage (it was literally a garage---like a car repair place, converted into a "club") in the mid-80’s, and there was an opening act whose name I had not before seen or heard. They started their set, and my girlfriend and I looked in disbelief at each other---they were grrreat! Yup, it was Los Lobos, who had not yet gotten a record deal. I was an instant fan, and still love them to death.
That girlfriend had great taste in music---her favorite band beside The Plimsouls was The Lyres, her favorite rocker Dave Edmunds. Unfortunately, she turned into a pothead, one thing I cannot abide!
