The reason for his unique attire as he explained, is to symbolize that people are all the same and all equal.He likes to believe that, anyone could be the person behind the mask, and anyone can achieve amazing things.
The song "unity" is a song Alan Walker made with his die-hard fans, who are known as “Walkers” and then the song was sang by a lady know as Sapphire.She is a talented emerging singer-songwriter from London, United Kingdom. Born in 2003.
This song is about love and unity, and how people would overcome obstacles just to see each other. Even if it means walking a thousand miles.
“Unity” is a singular noun which we would use to classify one entity, not two or more. But that’s the whole point. Alan Walker and the Walkers and any listener who may feel this way about another, present themselves as a single entity.
This song is so emotional, as it reminds me of people who have always been here for me and by me. Through the ups and downs and the good and bad.
The line that says "we are not alone,we are family" tells us so much about this beautiful song.
Below is the lyrics of "unity" by Alan walker.
"Unity"
In the dark of night
The stars light up the sky
We see them flying free
That's just like you and me
Everyone is lonely sometimes
But I would walk a thousand miles to see your eyes
You are not alone, we are family
Hold me, let's escape all this reality
You are my symphony
By your side, we are unity
You are my energy
My guiding light, we are unity
(We are, we are)
We are unity
(We are, we are)
We are unity
Although the rain might pour
A thunder starts to roar
The lightning wakes the wave
But through it, we are brave
Everyone is lonely sometimes
But I would walk a thousand miles to see your eyes
You are not alone, we are family
Hold me, let's escape all this reality
You are my symphony
By your side, we are unity
(We are unity)
You are my energy
My guiding light, we are unity
(We are, we are)
We are unity
(We are, we are)
We are unity
We are unity
You are my symphony (We are)
By your side
(We are, we are unity, unity)
You are my energy
My guiding light (We are unity)
We are unity
We are unity
