Ghost Train Orchestra is a Brooklyn-based jazz and chamber ensemble led by Boston-based musician Brian Carpenter. The band formed in 2006 when an historic theater in Boston commissioned Carpenter as musical director for its 90th year celebration. For the commission, Carpenter transcribed and arranged a set of overlooked music from late 1920s Chicago and Harlem and formed a side project from his regular band Beat Circus to perform it. The following year the group started performing under the name Ghost Train Orchestra.

Alexander Lafayette Chew Wilder was an American composer.
