Basically it's a folk metal song about Equestrian history

I can play/record Tin Whistle and Melodica, but I'm in need of collab partners for most of the other parts.
Are there any Guitarists, Violinists or metal Vocalists (screaming/growling) out there who would be interested in helping out?
Here's a link to the WIP. It's only a midi right now, and there are no vocals yet, but it gives a basic idea of the arrangement (which is not set in stone. If you have any ideas for things I should change, let me know!)
Lyrics:
All the world was covered in ice
Everypony hated, quarrelled and fought
Until the power of friendship
Made them unite
The spirits of frost met the hope of love
And screamed as they returned above
But from the sky they left behind
The genesis of changeling kind
The scaled ones retook their land
The dragons treasured all they found
Cities drenched in fiery breath
And they did nothing but collect
The form of ponies changelings took
But their black hearts soon overturned
Hungry for love they scoured the world
And feasted as everything burned
This is Equestria
Together we will take back our land
This is Equestria
We will not suffer at evil's hand
Before the blaze could burn all away
The dragons were drowned in chocolate rain
And upon the throne pure chaos sat
And all was turned upside down
The draconequus met the changeling queen
And together they ruled over everything
Disharmony left all ponies in
Fear and strife
United ponies faced their foes
But Discord's army stopped them cold
And the tyrant laughed at all his little
Toys
Malignant their deity ruled
All who tried to stop him fooled
Held by ties and bonds they could not
Break
This is Equestria
Together we will take back our land
This is Equestria
We will not suffer at evil's hand
This is Equestria
Together we will take back our land
All as one we stand
We will not suffer at evil's hand
From the depths of Everfree
Two sisters like nopony'd seen
Wielded power beyond belief
The elements of harmony
At their head a bird of light
The phoenix rose – majestic sight
Purging light gave strength to those
Who'd given up the fight
From the towns the royal guard was formed
And forward they thrust through changeling hordes
The light of the elements shining through
The reign of Discord's mind
From the scene the changelings flew
Spread across the entire world
And defenceless Discord fell
To his demise
Thanks for listening!
