This cancellation of a flat making you wild (7)

I haven't cracked this one yet — but the brilliant team at Times for the Times have:

in music a “natural” is an accidental note  (C, D, E, F, G, A or B) played without being a sharp or flat, marked by “♮”> on the stave if the key signature would expect it to be sharp or flat. At least, I think that’s what I remember from my piano lessons. Wild here meaning natural as in “re-wilding” meaning returning to a natural state.
