Terry Brock's first professional job in the music business was as a vocalist on the Kansas album Drastic Measures in 1983. He also toured with Kansas in support of that album and has worked with them on many other projects to date, including the band Seventh Key with Kansas bassist Billy Greer and featuring former Kansas violinist Robby Steinhardt. Interestingly enough, that year Terry also performed the LeRoux song "Addicted" with members Leon Medica and Tony Haselden at The Atlanta Music And Tennis Festival.
