We're so proud: Though only 26 years old, Houston native Ayman Harper has danced with companies in Frankfurt, the Netherlands and Chicago. And now that he's back home, he's making strides as a choreographer. This weekend the wunderkind will premiere M Saudade, a contemporary piece that deals loosely with AIDS and the sickness and loss it brings. Saudade, a Portuguese word, refers to a "yearning or melancholy for what is missing from one's life," and Harper's dancers respond with a duet set to experimental "hospital" sounds and an abstract sex-ed class. Show a native son some love at 8 p.m. tonight.
