“Kurt dove into the photo pit, and spoke right into my camera and said; ’…this is known as the blues scale…’ as he wailed away discordantly on his guitar with a Feederz sticker on it. And then he dove into the crowd, should be a cool shot. At the end of the set, during the "noise song”, he ran across the stage and tossed himself right into Grohl’s kit. Best show for them so far on this tour"
