Ken,

Mr. Gunn is performing the title role in Billy Budd at the San
Francisco Opera on September 26 and October 1, 6, 9, 12, and 17 this
fall. Individual tickets usually go on sale in mid-August if you're
interested.

He is at Seattle Opera in Florencia en al Amazonas next March --
sorry I don't have the exact dates, but their website would.

And I haven't seen this mentioned on this site yet, but MetManiac
lists him in the cast for the Met premiere of An American Tragedy, a
new opera by Tobias Picker based on the Dreiser novel (also the
source of the Taylor/Clift film A Place in the Sun). That's sometime
in 2005.

I hope that's helpful -- if I hear of any more I'll let you know.
Patrick
