I don't know which members of Clojure/core will be instructing this class; but I was at a Pragmatic Studio Clojure Programming session in 2010 and it was very good.
That one was lead by Rich Hickey and Stuart Halloway, but some of the most interesting parts of the class were listening in on conversations between David Liebke (the OP of this submission / author of Incanter), Rich and Stuart talking about Incanter and various moving parts inside Clojure.
I would imagine this class would also be quite good, no matter who leads it. One of the things that I've noticed about the Clojure community is that the people who know it well seem to be truly fluent in it as though it were a spoken language. This literary way of considering software seems to lead to interesting conversations about ways to solve problems that are applicable to many other languages, not just Clojure.
tl;dr: These guys are pretty fucking smart, this class will probably be awesome.
