In an interview with magazine "JazzTimes", Haslip said he was surrounded by music as a young boy, from visiting nightclubs and concert venues to his peers. He explains that there was music in his house as well, from his older brother Gabriel listening to classic jazz, his father listening to Latin and orchestra jazz and his aunt listening to "sappy stuff like Jerry Vale and Johnny Mathis". In high school, Haslip created his first band called Soul Mine with his high school classmates, playing soul music at school dances and parties.
