If you love the expressiveness of S-expressions but hate the super noisy parenthesis, check the sugar version, called "sweet-expressions". http://readable.sourceforge.net/

Clojure managed to keep the Lisp expressiveness while keeping the parentheses nesting low. I don't think I can list every Clojure feature that aids this goal but here's a few:

* bindings (let forms & similar) make implicit pairs, so it's (let [a 1 b 2] ...) instead of (let ((a 1) (b 2)) ...)

* square brackets as shorthand for vectors - the nesting level might be the same, but the second kind of brackets somehow helps the brain find the way in the parenthesis jungle.

* lots of helpful macros (e.g. -> and ->>) and other helpers that help write terse code with low nesting. #(+ 5 %) as shorthand for (fn [x] (+5 x))
