Kastle was born in Palm Beach, Florida, and began playing piano at age eight in 1966, learning to play by ear. "He's a musical genius." said his former piano teacher. "I remember he walked In and played the Hungarian Rhapsody No. 2 by Franz Liszt after hearing it on the Tom and Jerry cartoon," she said. "Back then, he couldn't even read music." Kastle studied with Ivan Davis. He began composing piano concertos as a teenager while studying with Davis. He continued his studies as a piano major at the University of North Texas, where he was expelled for calling in sick on his final recital. An official at the music department recalled Kastle, but said that neither he nor anyone else could remember enough about the case to comment. Kastle said that it was his refusal to dress formally for concerts that ultimately got him expelled from the music department. He later made monthly performances at clubs in Venice and Santa Monica, California where he built a following of young, often college-age, listeners.
