I am honestly curious what you have against Clojure. I dabbed with CL and Clojure, not as much as I would have liked to, but for me they felt similar. I would be curious to have a list of things that can easily be achieved with CL but not with Clojure.
Common Lisp is a multi-paradigm language (imperative, functional, object-oriented) in the Lisp 1 / Maclisp tradition. It has a language spec and multiple different, but very compatible, implementations. Among its goals are portability across different machines/systems, efficiency, power and stability. Thus complex Lisp software can be ported or written in Common Lisp and usually runs on top of several implementations (examples: Maxima, Axiom, ACL2, ACT-R, Common Lisp Music, ...).
"Clojure is predominantly a functional programming language, and features a rich set of immutable, persistent data structures. When mutable state is needed, Clojure offers a software transactional memory system and reactive Agent system that ensure clean, correct, multithreaded designs."
