If Brock's work is not as controversial as that might sound, there is some nervousness at NVA HQ about the impact of another piece, dealing with sexuality and performed by Caroline Aldred and Jamie Owen.

Through their exploration of the sex act, derived from study with a yogi from Bali, Shunyata, the couple set out to show the difference between pornography and the sacredness of sexuality.

To illustrate their belief that sex can be used to reach higher levels of consciousness, the first half of the seven-minute performance shows the opposite -- sex as pornography. ''It is very confrontational. People will either turn their heads away or they will respond,'' said Aldred.
