(The word "unwind" can be used here in the sense of relaxing or letting go, though it's a bit more figurative. If we were to use "perform" or another verb related to a choir, it would make more sense.)

(“Beyond” works here when referring to distant places.)

(Enjoying festivals does mean something special.)
