"**** The 13-piece all-star salsa big band Spanish Harlem Orchestra celebrates their 15-year anniversary in grand style with Anniversary, their sixth studio album. Champions of salsa dura ("hard salsa"), this is a band whose technical skill is matched only by their consistent high energy. They have three lead vocalists, so the chorus singing is also very high quality—an essential part of a strong salsa performance. Opener "Esa Nena" is a fine introduction to the group's body-shaking groove, and the program rarely lets up after that."
