The Ballet Theatre of Maryland and guest choreographer Alex Ossadnik explore the human condition, from a light airy romance to a quest for dominance and submission, in this weekend's performances of "Bagatelles," "The Rite of Spring" and "Postcard From Vienna." "Bagatelles," set to music by Antonin Dvorak, is an abstract ballet performed by six dancers -- Christi Bleakly, Sarah Cincotta, Kelly Hoenig, Jaime Lawton, Robert Michalski and Anmarie B. Touloumis -- who flirt with love and romance. In "The Rite of Spring," soloists Anmarie B. Touloumis, Jaime Lawton, Christi Bleakly and Sarah Cincotta, along with guest artist Bat-Erdene Udval, depict the struggle that exists between those who have power and others who grapple for it. Ossadnik, originally from Germany, based the choreography for "The Rite of Spring" on life in Germany after the fall of the Berlin wall. "Growing up in East Germany and having seen the whole power structure completely crumble . . . all of a sudden there were people who were normally in charge who had completely lost their power," Ossadnik said. "I tried to capture that in this work." The entire company performs the final piece, "Postcard From Vienna," to three waltzes by Johann Strauss. This is the last production of the Ballet Theatre's 2002-03 season, which was dedicated to late BTM founder and artistic director Edward Stewart. 8 p.m. Saturday and 3 p.m. Sunday. Maryland Hall for the Creative Arts, 801 Chase St., Annapolis. $31-$41; children, $26-$36. 410-263-2909.
