Rehearing this highly acclaimed, multiple-Grammy-winning album recently, I suddenly realized what the hype was about Carlos Santana. Other musicians who play guitar might show off their skills on the electric guitar via flashy high notes and runs and scales. Santana, on the other hand, electrifies in a different way: when he's at his best, he makes his instrument sing as powerfully as the human voice. For an example, go to "El Farol," Track 11 on this disc: who knew an electric guitar could sound so low-key and mournful?
