OSTIN MEMBRENO is a classically trained pianist, vocalist (dramatic bass baritone) and composer/songwriter. While Ostin`s academic background lies in classical voice and piano education, his musical life began as a young teenager with the electric guitar and rock music. Before deciding to study music professionally, Ostin attended private lessons for many years. Upon encountering the depth and beauty of classical music, he desired a deeper understanding of what he was hearing to elevate his own compositions. The easiest and best way to do this, he concluded, was to learn the piano and read the pieces himslef. Studying under a variety of different teachers during those years, he grew up experiencing many effective styles of teaching. While serving as a church musician for local parishes, Ostin was given the opportunity to perform weekly for hundreds of parishioners. In this time, he also directed and accompanied church choirs in preparation for holiday services.
Between classical piano and voice, Ostin has performed at the professional level dozens of times during his attendance at UMass Dartmouth. Ostin has sung with the university`s choir, their exclusive audition-only a cappella chamber choir, and the university`s Opera ensemble.
