This CD can be divided into two parts, really. There is the more traditional Santana world music sound, and the artist duet sound. Both are good, however, fans who only know the CD from the mainstream single "Smooth" are definately missing out on a lot more musical depth that is present here. Of the songs that do not have the help of any outside artists, (De La) Yaleo best showcases Santana's salsa influences and world music sensibility. Most of the duets are quite good, especially Put Your Lights On with Everlast, which has a downbeat mood to match the lyrics of the song, Love of My Life with Dave Matthews, which sounds very much like a Dave Matthews Band song guest starring Carlos Santana on the guitar, and Corazon Espinado with Mana, a great rock en Espaol song. Overall, the entire CD is good, and worth owning.
