An occasional swoosh across the crowd from a giant blade like the one at the end of Indiana Jones & The Last Crusade should keep the phone-holding hands down.
When I was young I briefly joined a band who were trying to "make it". They had management and label interest and all that crap and I despised every second of it. That scene was not for me. I love music but loathe the business.
Projecting coolness onto my young self, it would be Celtic Frost - To Mega Therion and Watchtower - Energetic Disassembly
In reality, it was Now That's What I Call Music 6 and Hits! The Album 3
Sounds like you have. It's very old news

Yep, Hammett on one side of the stage playing Greeny, Trujillo on the other playing Jaco's Bass of Doom. It's fantastic that both instruments still get played and the music snobs get to gnash their teeth and lament that neither instrument is locked in a safe somewhere, of no use to anyone.
There's enough spurious information on the packet there to make me walk away. "Our wires are manufactured in the USA" but the strings are Made in Korea. The sham patent trying to copy Elixir pack design. It all screams yellow-pack.
Not so different. Nevermore went for a truly different approach. Disturbed heard it and, years later, used it as a template to make a commercially bombastic version, devoid of any subtlety or feeling, cramming faux emotion down the throat of the listener with all the grace of a wrecking ball and with none of the guile or creativity of Nevermore.
The 'oo. The muscle of Live At Leeds (or even the Isle of Wight) vs the puny studio albums up to that point is like two different bands. Can't Live Without It by Gang Green is wonderful, with a real energy which the albums don't quite match. Rush in Rio pumps a lot of fire into songs from their tamer 80's material.
I wouldn't say If You Want Blood easily outdoes their studio stuff. The likes of Powerage still sound fantastic.
