Miguel ZenÃ³n, Esta Plena (Marsalis Music). The alto saxophonist and composer illuminates and elevates la plena, the peoples’ music of his native Puerto Rico. ZenÃ³n augments his quartet with percussionists playing pandero, seguidor and requinto drums to provide the music’s rhythmic heart. ZenÃ³n’s playing further establishes him as one of the most important young soloists in jazz. Pianist Luis Perdomo, bassist Hans Glawischnig and drummer Henry Cole are impressive throughout. ZenÃ³n aids understanding of the music with a scholarly liner essay tracing the history and cultural importance of la plena.
