Santana

In theory, the polyrhythms intensified the momentum while the low-definition songwriting served the freeflow gestalt. In fact, the Latin lilt lightened the beat and the flow remained muddy indeed. So the electricity generated by the percussion-heavy opening cut comes as a pleasant surprise, and the movement of what follows is a surprising pleasure. New second guitarist Neal Schon deserves special thanks for crowding out Gregg Rolie's organ. Maybe soon he'll come up with more than one idea per solo. (Grade: B)
