I believe that it is a wonderful video. A very moving and spiritual one about gratitude, thanksgiving, appreciation, praise, rejoicing, celebration, joy because the gift of music and the vocation/calling of music = is a window TO the skies and a window FROM the skies. Think of all the ways music, in particular good music, has positively influenced us, shaped us, been there for us throughout our life - in good times and difficult times, how music has been a form of prayer. “Turn each song into a prayer.” (U2 – Always)
I agree with an additional layer of interpretation by scha: “Personally I love this video, and I think this is very adequate for the 30th anniversary. For me it says that although now they are also in the Pantheon of Music Legends, they have not forgotten the reason they started all this: because they were fans of music.”
