Swan Lake, Royal Albert Hall, Kensington Gore, London SW7 (0171-589 8212) today to 26 June
Another chance to see English National Ballet's arena Swan Lake: it's both a nightmare aviary for pursed-lipped ballet purists and an exciting Riverdance-style show (without the tap-dancers' shoes) for unfettered adventurers. Go for the dramatic sweep and vast in-the-round patterns, not for subtlety or fidelity to tradition. Expect some of the action to be turned away from you; avoid, if seated on the end of a row, poking a foot and tripping up the characters entering and exiting via the aisles. Young, enchanting Tamara Rojo dances some performances, opposite Patrick Armand, returned to the company after a long absence.
