In the early 1970s, Larry and Fonce Mizell moved to California to start their own company, Sky High Productions.
[4] As an electrical engineer, Larry Mizell performed testing and reliability work on the Lunar Module for the NASA Apollo program.
[citation needed] Alphonso Mizell was a member of The Corporation, the Motown hit-making production team that wrote and produced all of The Jackson 5's early hits from 1969 through 1971, including "I Want You Back," "ABC," "The Love You Save," "Mama's Pearl," and "Maybe Tomorrow."
The Corporation also consisted of Motown founder Berry Gordy plus writer-producers Deke Richards, who brought Fonce to the company, and Freddie Perren, a classmate of the Mizells at Howard who also later worked for Sky High Productions.
When Motown moved to Los Angeles, the Mizells joined up with trumpet player Donald Byrd under whom they had studied while at Howard University.
