original youtube comments from quarkhenares, (director of a recent chicosci video who just happened to be there and uploaded this video):

For a very brief time in 2002, after Ely Buendia left the Eraserheads, the band continued on with Kris Gorra as Ely's replacement.

After the Aug 2008 reunion concert was cut short due to unforeseen and sad circumstances, the remaining members decided to debrief and talk in Saguijo. Everyone was in high spirts when the info came out that Ely was well and good, and maybe as an act of celebration (or simply because nabitin sila sa concert), they decided to jam when there was no one left. The result is one of the most heartfelt and inspiring performances i've ever seen in my life. You'll have to forgive me singing out loud at one point. I couldn't help it.
