Amber Bullock, winner of BET's 2011 Sunday Best, overcame personal challenges and impressed judges like Kirk Franklin and Donnie McClurkin during her audition in Dallas. Despite setbacks, including a car accident and her mother's illness, Bullock's standout performance of "A City Called Heaven" secured her victory over finalists Michael Pugh and Andrea Helms. Her debut EP, Thank You, featuring the winning song, was released by Matthew Knowles' Music World Gospel label later that year.
