While GnR delivered the goods at AT&T Stadium last night, there were a ton of cries from the crowd over 'terrible sound quality.'

In many corners around the web, you'll find tons of pics and videos from fans that really enjoyed themselves. Equally, you'll find those complaining about the sound quality. Mostly from fans directly in front and elevated above the stage. If you've ever seen a show at OKC's Chesapeake Energy Arena, you'll know that sports-dome's aren't exactly nice to music. Echoing around concrete walls, making for a deafening experience.

Pro-Tip: Always take rubber earplugs to concerts, even the outdoor shows. Rubber plugs won't muffle the music, they'll cut the high frequency harshness and make the low range acceptable. These are the plugs we grab on the cheap.

The most noticeable thing everyone talked about was the crowd attendance. AT&T Stadium has some 80,000 seats... but an overall capacity of 111,000 people. Estimates from the venue estimate last nights crowd somewhere around 35,000 people. Far less than what was expected.

Regardless, it would have been a cool show to see unfold live in person. Here's more of their performance.
