MLA has provided acoustical engineering and audio processing equipment for several World Expositions including Expo ’86 in Vancouver, Canada, Expo ’88 in Brisbane, Australia, Expo ’92 in Seville, Spain, and Expo ’93 in Daejeon, Korea.

Expo ’86 commemorated Vancouver's centennial and was the first time the United States, China, and the Soviet Union exhibited together in North America. The theme was Transportation and Communication. Canada's pavilion was located on a pier not contiguous with the rest of the site. That pier is now Canada Place and is one of Vancouver's most recognizable landmarks.

MLA worked with Bob Rogers Entertainment and Walt Disney on the Spirit Lodge show in the General Motors Pavilion. The show featured an Indian lodge where a story teller told the legend of a magic canoe that was able to transform its size to seat an entire village or shrink to comfortably fit a small child. It needed only a wish and one dip of the paddle and the canoe would instantly take its occupant anywhere he or she wished to go.

When the story teller was finished he sat on his stool, bowed his head in thanks and disappeared into thin air. The presentation was only nine minutes long but people waited in excess of three hours to see it.
