In 1990, LaBrie learned that American progressive metal band Dream Theater was looking for a new singer, so he submitted a tape and was quickly flown to New York for a full audition. The tryout went well, and he was chosen ahead of 200 other hopefuls to fill the full-time vocalist position in that band.
