Over the past 22 years, choreographer Scott Wells has dealt with the relationship of dance and sports (which included putting athletes on stage) and he has surveyed the anxiety surrounding impending fatherhood. “The why ask why we dance dance,” the premiere of which concluded Friday evening’s opening of Scott Wells and Dancers’ season at ODC Theater, is a quasi-serious romp that delivers a bundle of home truths about dance and allows Wells to fuse speech and movement in a manner, which at its best, is unbeatable. Next, Michaela Burns recalls her aborted career in ballet school and interrupts the monologue to waltz with Jared Wiltse. Voice-overs both direct the dancers and question their movement, while they are dancing; thus the three women who wonder, “Why are we always moving in unison?” The men call for different music, they reject bluegrass and “Nutcracker,” and settle for hard rock. The often fierce dancing is based on contact improvisation; women hurl their bodies into their colleagues’ waiting arms, or a pair will take to the floor and maneuver their cantilevered bodies into architectural forms. The opening gives us the dancers kneeling, like dolls, backs to us, playing harmonicas, then toppling over, a terrific gag, and the end of the piece is clever, too.
