Query: First volume of a superior set of early Brazilian rock

"Jovem guarda" was the name of Brazil's prefab early-'60s teen rock scene... This series is one of the stronger sets of this style of music, avoiding the wimpiness and bland pop vocals of similar collections on Polygram -- much perkier, Little Eva-style stuff. It's cute, but also fun!
