Here is an image from an "old school period" that most modern metal heads that are young and starting new bands have forgotten these days.
This gives them an idea of the right image to uphold when starting a "METAL BAND". Hats,baggy pants,shorts..ect....is just plain right out what is known as "Tunnel Hat".
I am 100% against the "Tunnel Hat" image of so-called "metal bands" if thats what they call themselves. Dress what ever the hell they want outside of the "band"...but when
onstage,in magazine photos,in CD booklets....where ever the band is promoted..then yes they should have a metal image, just like Judas Priest does. This is very important for metal.
