Angela Isart, Lead Singer and Band Leader

Angela Isart, Lead Singer and Band Leader

Angela Isart has been a lead singer for local Houston cover bands since 2010. She founded A Sure Thing along with James Langenbuch, former bassist, and guitarist, Miguel Thornton in August of 2014. Angela believes her wide vocal range stems from her years in church, high school, and college choirs as a first soprano where she was a featured soloist and first soprano and alto for small ensemble. She received a scholarship for voice and attended San Jacinto College North. She received her teaching degree in 1998 from The University of Houston-Downtown, graduating with honors, and when not performing, works for promoting, booking, and managing A Sure Thing. For her, it is a labor of love and a dream come true to sing with such an accomplished group of musicians and friends. The men in her band have had a major impact on her life musically as well as personally, and she is proud to have created a band that dedicated and loyal to the music, the group, and to one another. The musical influences that have helped shape her own performances include Patsy Cline, Anne Wilson, Bette Midler, Barbara Streisand, Donna Summer, Chaka Khan, Prince, Beyonce, Bruno Mars, Mick Jagger, Steven Tyler, Steve Perry, and Tina Turner to name a few.
