This is London's version of New York City Center's Fall For Dance festival. Two nights of mixed dance styles, cheap tickets (£10, or £5 standing) - ideal for a taster. Most of the companies performing will be back at Sadler's Wells later in the season, so it's also a great marketing tool for them!
The line-up looks good to me (as per SW's website):
American Ballet Theatre - White Swan Pas de Deux performed by Veronica Part and David Hallberg.
Flying Steps - World-beating virtuoso hip hop styles from Germany.
Jasmin Vardimon (Sunday only) - Intensely physical dance-theatre in an extract from Vardimon's Yesterday.
Matthew Bourne's New Adventures -Enjoy the Swan and Prince Duet from Act Two of Swan Lake.
Rojas & Rodriguez - The stars of Nuevo Ballet Espanol bring some authentic flamenco flavour.
Russell Maliphant - Former Royal Ballet dancer Dana Fouras performs Maliphant's sublime Two.
Traces (Saturday only)- Experience circus as you've never seen it before.
