15-17 Oct (Sat perf at 5pm). Large retrospective in Dance Umbrella for the often fascinating US modernist Trisha Brown starts with her company in landmark Glacial Decoy (1979), Opal Loop (1980) and latest creation L'Amour au theatre (drawing on Rameau's opera Hippolyte et Aricie). Before each show there are performances of her 1970 Floor of the Forest in the foyer, a sculpture of clothing animated by dancers. www.danceumbrella.co.uk
