Scheme is a lisp made from scratch. It bets on clarity, functional programming, minimalism and elegance. There is a perfect introductory book "Structure and Interpretation of Computer Programs"[2] which is a worth read even if you don't want to program in Scheme in the future.
I haven't used Clojure, but from what I've heard it's a modern functional lisp which bets on parallelism and interop between environments.
There are more lisp dialects like PicoLisp, but I know about them even less than about the Clojure, so you'll have to investigate options by yourself. I'm a Common Lisp programmer, so I can recommend that – "the profound enlightenment experience", as Eric Raymond put it.
