The real power of Lisp becomes apparent when you develop programs top-down with very general data structures with their own accessors and a liberal use of higher-order functions. I still think that Winston & Horn's classic Lisp (3rd ed.) conveys these ideas very well. SICP is also very good at it, but it's based on Scheme.
