Machine Head rocker Phil Demmel ended the band's concert in Virginia on Sunday in dramatic fashion - he collapsed from dehydration while performing the penultimate song.

The guitarist complained about feeling lightheaded moments before passing out on stage at the Nissan Theater in Bristow. Drummer Dave McClain reveals, "That was a scary moment for all of us. Seeing your friend collapse like that is something that nobody wants to experience. He's doing much better now and taking it easy on the bus."

Demmel is expected back on stage in Darien Lake, New York on Tuesday to close the band's successful Rockstar Mayhem tour.
