Just pick up the video series from Rich Hickey himself http://blip.tv/clojure

And 'Programming Clojure' (among others). It's a nice concise read. (http://www.amazon.com/Programming-Clojure-Stuart-Halloway/dp...)

Edit: blip.tv is terrible for navigation. You have to click a few times to go to page 5 of the channel. Start there.

You might check out the book "Seven Languages in Seven Weeks" which has a chapter on Clojure (and Scala, Ruby, Io, Prolog, Erlang and Haskell too). I took a class that used it and I thought the format was quite good.
