Plena Libre is a plena and bomba group. Their music follows traditional forms while also drawing on other styles of music. In a biographical summary of the group, Steve Huey of Allmusic observed that the group's blend of "contemporary dance arrangements... (and) the long-ignored Puerto Rican folklore-derived plena style... return(ed) the style to prominence." A popular live act over the course of a 20-year, 14-album career, the Puerto Rican ensemble are known for strong musicianship; for example, Chris Nickson of Allmusic, in noting the blending of jazz elements with plena on the Mas Libre CD, described the group's delivery of said as "highly accomplished".
