“I think it was the 1st live music performance I ever saw indoors. Bob Seger...”
Yep.... same here. Saw them in Austin in the early 80’s in the nose-bleed section. Fortunately back then, you could actually roam around the venue all the way to the stage if you liked. Couldn’t get that close though as the mega-speakers they were using was doing a number on my body. Made it about 40-50 feet to the stage and had to turn back as the pressure waves were too intense.
Speaking of Texas...my 1st outdoor was Allen Park HS. Michigan...Ted Nugent & the Amboy Dukes.
