Solo performer Tomás Kubínek has a bio that reads like a John Irving novel: Smuggled out of Prague at age 3, lived in a refugee camp in Austria before emigrating to Canada where, at age 5, he saw his first circus. His own circus debut, as a teenager was "as the rear half of a two-person horse." He has since graduated from horse duty to his own "exuberant blend of absurdist theatre and circus magic" and the title, "certified lunatic and master of the impossible." He'll perform at Diana Wortham Theatre on Saturday, Jan. 19. 8 p.m., $35 general/$30 students/$15 children. http://www.dwtheatre.com.
