Sweating out your week from hell is always more fun with live accompaniment. Every Saturday at SpaceSpace, spiritual (and aerobic) rescue is available to all ages and ability levels via two vibrant Afro-Caribbean-based dance classes, with many of the Twin Cities' finest drummers on hand to keep the beat pure. Beginning at 11 a.m., Morris Johnson serves up his hybrid "Langanese" style to divas and beginners who enjoy a little Southern charm with their sambas and merengues. Patricia Brown follows at 1 p.m., encouraging her students with shouts of "Joy!" and an infectious smile that gives rise to muscles you never knew you had. Each two-hour class costs $9.
