"Sacrament Of Wilderness" by Nightwish, album: Oceanborn (1998)

Naked in midwinter magic
Lies an angel in the snow
- The frozen figure crossed by tracks of wolves
An encounter, symbolic, yet truthful
With a hungry choir of woods
An agreement immemorial to be born

Dulcet elvenharps from a dryad forest
Accompany all charming tunes
of a sacrament by a campfire
A promise between the tameless
and the one with a tool
Tonight the journey from cave begins

I want to hunt with the tameless
I want to learn the wisdom of mountains afar
we will honor the angel in the snow
We will make the streams for our children flow

Wrapped in furs beneath the northern lights
From my cave I watch the land untamed
And wonder if some becoming season
will make the angel melt in shame

A visionary represantation of nature and wildereness in the past. In the end there is anxiety about the future of this natural balance that make the angel of nature melt in shame

“Creek Mary's Blood” by Nightwish, Album: Once (2004)

Soon I will be here no more
You'll hear my tale
Through my blood
Through my people
And the eagle's cry
The bear within will never lay to rest

Wandering on Horizon Road
Following the trail of tears

White man came
Saw the blessed land
We cared, you took
You fought, we lost
Not the war but an unfair fight
Sceneries painted beautiful in blood

Wandering on Horizon Road
Following the trail of tears
Once we were here
Where we have lived since the world began
Since time itself gave us this land

Our souls will join again the wild
Our home in peace 'n war 'n death

Wandering on Horizon Road
Following the trail of tears
Once we were here
Where we have lived since the world began
Since time itself gave us this land

"Hanhepi iyuho mi ihanbla ohinni yelo

O sunkmanitutankapi hena,
sunkawakanpi watogha hena,

oblaye t'ankapi oihankesni hena

T'at'epi kin asni kiyasni he
akatanhanpi iwankal

Oblaye t'anka kin
osicesni mitakuyepi òn

Makoce kin wakan
WakanTanka kin òn

Miwicala ohinni - Hanhepi iyuha
kici - Anpetu iyuha kici yelo

Mi yececa hehaka kin yelo, na
ni yececa sunkmanitutankapi

kin ka mikaga wowasaka isom

Uncipi tuweni nitaku keyas ta k'u

Unwakupi e'cela e wiconi
wanji unmakainapi ta yelo

Anpetu waste e wan olowan
le talowan winyan ta yelo

Unwanagi pi lel e nita it'okab o'ta ye

Untapi it'okab o'ta

Na e kte ena òn hanska ohakap
ni itansni a'u nita ihanke yelo"

Translation:
"I still dream every night
Of them wolves, them mustangs, those endless prairies
The restless winds over mountaintops
The unspoilt frontier of my kith n`kin
The hallowed land of the Great Spirit
I still believe
In every night
In every day
I am like the caribou
And you like the wolves that make me stronger
We never owed you anything
Our only debt is one life for our Mother
It was a good day to chant this song
For Her
Our spirit was here long before you
Long before us
And long will it be after your pride brings you to your end"

Another song about the elimination of Indians in America by the white invaders and the degradation of culture and life of their remnants. Sung in native language the rest of the song is a lament by an elder Indian of what has been lost and been spread from mouth to mouth through the survived generations with the hope for a future salvation by returning again to their roots.
The song is inspired by the homonymous historical novel based on true events by Dee Brown which is refered to the adventures of an Indian woman and generally the Creek Nation. We read in Amazon.com a customer’s review about this novel:

This novel concerns Mary Musgrove who was the Creek wife of John Musgrove, an Indian Trader who had a trading post near the Savannah River when Oglethorpe brought the first settlers to Georgia in 1731. After Mary's husband was killed, she was eventually forced to abandon her home and people. The novel sets out the problems she encountered and follows her children (Mary's Blood) on the trail of tears westward and ends up with some of her decendants involved in the battle of Little Big Horn. This novel transports the reader into the person of Mary Musgrove and allows us to feel the pains endured by the natives of this country during a period of disgraceful acts committed by some of our forefathers in the name of patriotism.
