The first two CDs are like no other kind of music . . .huge variety of percussion with great congas, bongos, and cowbell. . . . and lyrics and chanting in Spanish. Very festive and free, but takes some getting use to. The tracks with organ are the least hip. . .the ones with vibes are excellent. Unfortunately the 3rd disk in my copy was severely defective. . .the last seven tracks wouldn't play. If you can get a good copy of this, it is certainly a unique addition to a music collection.
