Limi-T 21 has been throwing merengue's hottest party for almost 25 years. And while younger artists have come along (not to mention the rise of urban bachata), the group still knows how to do just what the overly literal title of their umpteenth album suggests. The dancing and partying occurs in many forms: frenetic and buzzing, slower and more sedate ("A Mi Me Gusta," which finds this energetic band settling into middle age), jazz-hued ("No Llores Mas Por El") and, of course, hip-hop-infused (the incorrigibly fun "El Gallo y La Gallina"). That album title is also a command. So get busy.
