I saw this yesterday with dd (12) and ds (10) and they loved it. Great Fun!
It's a hip-hop dance urban fairytale set on the Ruff Endz estate with the characters such as Rap-On-Zel, Lil' Red, Jaxx, Wolf, Prince etc. living in a tower block. The story is narrated with some film footage as well. Great dancing, some funny characters and lots of good music (ranging from James Brown, R&B, Massive Attack, Prince and loads of other bits!).
We were lucky and got cheap preview tickets, but the previews end this week. There are cheap tickets on the balcony, but I wouldn't recommend that option as you would probably miss some stuff they do at the very front of the stage (plus they hopped off it a couple of times).
