Elixir seems much more like Clojure without the parens to me than Ruby. (Yes, I know Clojure can actually use fewer parens than the equivalent Java, just referring to the Lispy syntax in general.)

Dynamically typed, functional language with immutable data structures and a strong philosophy about how to best handle concurrency and scaling.

The key difference is JVM vs. Erlang VM as the base and all that implies.
