Seven Impale windshears

Out to it to talk to evolve to its future
Before it's done; create more
Vital, no, but it will be
In to it to hear to believe it
after it's gone; create more
Crucial, yes, it had to be done
Meet me when the wind changes
As the wind changed I saw myself turnout
Towards the flock turning inwards
In to it to hear I believed it
After I'm gone; create more
Thoughts I can believe in
Loud and clear the wind blew
As a bugle it sang
But still we hope it will change
