Miller was born in Louisville, Kentucky as one of seven children. She began singing professionally at the age of 15 and featured prominently in the Louisville music scene. She sang backup for Al Green, and opened for Mel Tormé and Lou Rawls. Her band was the first African American bands to play regularly at the Louisville Hyatt Hotel.
In 1984, while relocating to Los Angeles with her two children, Miller's rental truck broke down in Denver, and she decided to stay. Since then, she has performed in Colorado and beyond. A review in the Rocky Mountain News called her ‘a force of nature’, and her voice has been called[by whom?] ‘stunning, moving and powerful.’ She played at the Red Rocks Park and Amphitheater near Denver, at the White House for then President Bill Clinton, and for the Denver Broncos after their 1998 Super Bowl win. Miller has toured with the military five times, including playing at Iwo Jima. She has been a regular performer on the ETown Radio Show, airing on NPR's national affiliate stations. Her recorded voice greets visitors taking the trains to the main terminal at Denver International Airport.
In 2008 she launched Hazel Miller Entertainment and became a booking agent. She has sung with or opened for Julian Lennon, Peter, Paul & Mary, Charlie Musselwhite, James Taylor, James Brown, the Temptations, and many others. In addition, she toured for five years with Big Head Todd and the Monsters, and has performed at major jazz and music festivals throughout Colorado.
