This is the 10th year of Donald Byrd’s tenure as top dog at Spectrum Dance Theater. For the anniversary season’s studio show, Byrd has assembled a steamy-sounding lineup of sex and death: Crispin Spaeth’s Only You was choreographed as a tumbling, passionate valentine to its composer (and now Spaeth’s husband) Dale Sather. Back, sack and crack by Olivier Wevers is a suggestively titled “examination of sexuality” and “gender identity.” And Byrd’s A Meeting Place uses old instruments—the European lute and the Middle Eastern oud—“as a metaphor for cultures, weapons, and ideologies.” (Spectrum Dance Studio Theater, 800 Lake Washington Blvd,, 8 pm, $25, Nov 30–Dec 9)
