Albert Lavada Durst (January 12, 1913 – October 31, 1995), known as Dr. Hepcat, was an American blues pianist, singer, and baseball commentator who became the first black radio DJ in Texas, influential in the spread of rhythm and blues and rock and roll music. Durst was born in Austin, Texas, and learned to play piano as a child. He grew up playing barrelhouse blues locally, and developing a talent for hip rhythmic jive talk, which won him a position as announcer at Negro league baseball games in Austin.
