(DANCE) The Amsterdam-based company is renowned for its athletic and captivating blend of ballet and modern dance. Like the Montreal-based La La La Human Steps, Emio Greco’s troupe takes some astounding chances (things that shouldn’t quite work together) and ๏ฌnds sublime beauty and power in juxtaposing them. This is what dance is supposed to provide for an audience-physical prowess and artistic daring. (On the Boards, 100 W Roy St, 217-9888. 8 pm, $22.) NATE LIPPENS
