No matter how you slice it, it was actually their last performance, even if was an appearance with Patti Smith.
haha well I will slice it the real way... I have in my possesion the last ticket of a R.E.M. concert in their history, (front row) and the date is November 18, 2008.
Tell, argue, yell, or discuss whatever you wante Nate but I was there on the last ever concert of the band in the history, and that is something priceless.
Is it cool if you envy that, don't feel bad.
