I believe the correct spelling is Chris CINTRON. Following the Steve Stone debacle, he was the next singer that the band really liked. He was the first singer to work out the original vocal melody of Change of Seasons (as heard on the official I&W bootleg).
The record label was very cold to the idea of him being the new front man, and due to the Steve Stone incident, the band was not ready to commit to him, although they had been working with him on demoing new material. Ultimately, he was still rehearsing with DT when JLB’s demo tape arrived. After practice one night, the four guys pretended to go home for the night, Chris departed and the band returned to the rehearsal space to discuss JLB’s demo.
In the future, no need to die of curiosity. Just buy Rich's book Lifting Shadows.
