To 14 March, Lyric Theatre, Shaftesbury Avenue, London W1 (0171-494 5045)
Celebrate... the beauty of catastrophe. Hermann Nitsch, the ex-Vienna Actionist (one of whom is in prison for paedophilia, while another committed suicide) lives in a 13th-century castle in Austria where, periodically, he and his volunteers revel in "the joy of the terrible". Tapping into the theme of ritualistic suffering in all great art, Nitsch and his volunteers slaughter, crucify and disembowel farmyard animals in gory tableaux vivants. Thanks to exhibitions such as this, Orgies Mysteries Theatre, Nitsch is finding a wider audience.
