In a Latin music industry filled with so much plastico, Gilberto Santa Rosa is the real deal. The Puerto Rican sonero capitalizes on that reputation with the aptly titled Autentico. The first half of the disc walks a fine line, trying to reconcile the demands of salsa radio (the sensual "Sombra Loca") with the desires of the old school ("Traigo de Todo," which liberally quotes Palmieri's "Tirándote Flores") and the commercial realities of Puerto Rico's market ("El Rincón de Mis Ansias" features a powerful bomba; "Traigo" boasts of his abilities to bring everything from salsa to "reggaeton, como [Tego] Calderon"). The exciting news is that by the end, the old school wins. A three-song snapshot of classic salsa concludes Autentico (remember -- always end with what you want them to remember), with a lineup change that includes all-stars including Libre's Manny Oquendo and Andy Gonzalez, Tipica 73's montunero Sonny Bravo, saxman Mario Rivera, and a good-natured duel with vocalist José Alberto el Canario. These songs, and good deal of the ones preceding, including the powerful opener, "Piedras y Flores," make the latest from Sr. Santa Rosa one of the most exciting mainstream salsa releases of the year.
