Take a tour through music history – from chant to present day – through the lens of the motet. What's a "motet", you ask? Is it real, you ask? We are not entirely sure. Composer Mark Buller, whose music has been performed worldwide, and who has been commissioned by organizations like Houston Grand Opera, will be your tour guide. Get on board the great Classroom coaster. We have cupholders and a great soundsystem.
