This is my favorite song bar none. Awaken by the band Yes. It inspires me in every way possible. Musically is beyond anything I have heard before until the present day. The first half of the song sounds very eastern almost Hindu in style. The second half sounds very western almost like a Catholic mass. The two half’s come together in a way that reminds me that spiritually both east and west believe in the same core values but in different styles and expression. No matter our differences we are all one.
