Sudden impact
This is:
(a) a demonstration by PETA to protest the treatment of eels in Chinese seafood restaurants,
(b) the G train full of hipsters or
(c) Streb, the "extreme action" dance company that played the Prospect Park Bandshell last night.
Yes, it's Streb, whose death-defying "actioneers" flung themselves about on a perfect summer evening with a wild mix of daring abandon and precision teamwork. Elizabeth Streb, their choreographer, describes their work as "a mixture of slam dancing, exquisite and amazing human flight, and a wild action sport." It also includes this rig called the "whizzing gizmo," onto and off of which the company leap like crazed tree frogs.
Oh, and they also perform terrifying feats with two pendulum-like swinging cinder blocks. Real ones.
