Yes, I finally could see a Cirque Éloize performance, and it was during this Toronto Buskerfest 2010. For many years I was trying it but always something happened stopping me to go.
ID is the name of Cirque Éloize's last spectacle, and it is all around street acrobatic acts, much of it with street dance (Capoeria and hihop styles), bicycles, street climbing, etc. It seems that it has been a great success in its natal Montréal and they are trying to expand that success to Toronto and all over Canada.
The Toronto Buskerfest Cirque Éloize's performance I saw was only a 30-minute extract from the original spectacle (originally for an inner stage and not for street festivals), but it shows many of the impressive acts included in it: some street acrobatic dance, a play with a hoop, and acrobatics with a bicycle. Well, I said impressive acts, when actually there were not as impressive as they should be. After have seen the video you will agree with me that this was not the best way to introduce a very interesting modern circus company to any public, many of the movements during this performance had no strength nor projection, and some parts were almost bad performed. I guess it was because this wasn't the original performing plan and they were very aware of the danger of working on a stone stage; even do the bicycle acrobatic act is surprising and well done.
Now I'm looking forward to see this company performing on a theatrical stage (in October this year), and then add my opinion to that of many others who have seen Cirque Éloize before, that they are an amazing modern circus company with the similar level of quality than its big brother, Le Cirque du Soleil.
