I get good references from a wide range of music. Something who's been a good influence in the last few years is Qawwali music. If you listen to a Qawwali singer like Aziz Mian - he's like James Brown. Qawwali is like Pakistani gospel-jazz. It's emotional, but it's also improvised, and it's all about that sacred-and-profane tightrope.

Does art have a future? Performance genres like opera, theater, music and dance are thriving all over the world, but the visual arts have been in slow decline for nearly 40 years. No major figure of profound influence has emerged in painting or sculpture since the waning of Pop Art and the birth of Minimalism in the early 1970s.

I sang of leaves, of leaves of gold, and leaves of gold there grew.

Do you know what I've learned? That although ecstasy is the ability to stand outside yourself, dance is a way of rising up into space, of discovering new dimensions while still remaining in touch with your body. When you dance, the spiritual world and the real world manage to coexist quite happily. I think classical ballet dancers dance on pointe because they're simultaneously touching the earth and reaching up to the skies.

I am not immune to the lure of a signed record, flier or set list. The fact that your music heroes potentially had, in their own hands, the record you now have in yours is kind of cool. When the musician has departed, it can give the thing a unique power.

OPERA, n. A play representing life in another world, whose inhabitants have no speech but song, no motions but gestures and no postures but attitudes.
