Circa opens tonight

Circa, another boundary-pushing circus act (this time from Australia) opens at the Paramount tonight, as a joint presentation of Celebrity Series and ArtsEmerson. I feel comfortable promoting the show prior to seeing it as I caught Circa two summers ago at the Edinburgh Fringe - where they were pretty easily the strongest act I saw. Not for everyone, these acrobat-jock-dancers can be blithely cruel, and often take the circus into the darker corners of human relationships, both social and sexual.  One particular acrobatic meditation on sadomasochism - done, of course, in spike heels - is pretty much unforgettable.  Through Sunday.
