Ray Barretto's Taboo features a new, smaller version of his New World Spirit ensemble. Hector Martignon, who composes along with Barretto, is still here, as are Satoshi Takeishi, Ray Vega, and Jairo Moreno. Saxophonist Adam Kolker takes the sax chair vacated by Jay Rodriguez, and guitarist Alfredo Gonzales has not been replaced. The material is far jazzier on Taboo. Barretto explored the roots of Latin jazz as it transformed itself into the New York version of son and salsa on 2003's Hot Hands: Ancestral Messages, and Taboo serves as a guidebook to present and future tenses of Latin jazz. For starters, one can read between the lines that Ray Vega's charts have moved far a-field of the standard notions surrounding big band arrangements. Everything here feels fluid and relaxed; the playing leaves spontaneity in the air whether it is on a Barretto or a Martignon original, such as on "Bomba-Riquen," "99 MacDougal St," or something from the hard bop cannon by Nat Adderley and Oscar Brown, Jr., such as the classic "Work Song," or a modal tune like McCoy Tyner's "Effendi".
