I feel extraordinarily lucky to have seen the Alive 2007 set both in 2006 and 2007. I agree with Ben_J - this is the modern version of having been able to see something iconic, the only difference of course is that the immense amount of footage that exists of those moments have spread through the Internet for all to see.
I am grateful for the moments that Daft Punk's music has allowed me throughout my lifetime--I cannot adequately express the gratitude for their music to them, and it would be futile of me to do so.
Unfortunately, this is a disappointing end to a disappointing end. To have disappointment follow disappointment feels like I have wasted energy hoping that we would see something else from the duo. But how precisely to shed a tear for the first-world problems of fans that have been left out in the cold for decades.
With that said, these musicians will keep producing music. We will still hear the results of Thomas Bangalter and Guy-Manuel de Homem Christo as they work with other artists, produce others' work, and of course release music pseudonymously that we later find out is them.
And there is even a chance, of course, that Daft Punk itself is not done. There is a chance, of course, that these two french artists, renowned for their ability and their desire for control of their image, lauded for subversive plans for their art and their success in surprising their audience, intend for everyone to understand that what they were before is gone.
I would not be surprised if we see a phoenix rise from the ashes.
But I'm not hopeful.
Just sad.
