Col. Bruce Hampton, known as Atlanta's "Granddaddy of the Jam Scene" turned 70 on April 30 and performed at the "Hampton 70" gathering in his honor.

A fan's video showing the moment of Hampton's collapse emerged briefly on YouTube. It's since been taken down. The Atlanta Journal-Constitution viewed but did not post the clip.

Indeed, the horrible moment occurs several minutes into the final rocking number. Tragically, the music continues for a while after Hampton's collapse. The low lighting, crowded stage and configuration of the musicians probably kept people from realizing immediately what had happened. The video ends abruptly as everyone (perhaps the fan who posted it included) becomes aware of Hampton's situation.

The family has asked for privacy.
