I've had them about a half dozen times over the years and it's almost always been a mistake which makes them memorable.
Prince, Tacoma Dome, Purple Rain tour, mom hooked up the family with Purple Circle tix right up front and this was fantastic, first time that close to anything, and every experience went down hill from there.
The Cure at San Diego Arena, kiss kiss kiss me tour, too close as it sounded like shit with the reverb.
Iron Maiden, same venue, Powerslave tour, they had so much shit on the stage I couldn't see everything very well,and again with the reverb. Only positive is that I caught Steve Harris' Westham wristband that I keep ticketstubs from that year to this day.
Depeche Mode, Dodger Stadium, Violator tour, place was so freekin big that front row didn't mean shit.
Natalie Merchant, Cambridge Corn Exchange, Motherland tour, way too close for comfort, had to look straight up, and everytime she sat on a stool she'd have to cross her legs and I had to turn away because her bloomers were looking at me. Sound was spotty too.
Mary J. Blige, DAR Constitution Hall, No More Drama Tour, this show introduced me to the fact that front row at DAR sucks, too close, no leg room, too loud, all around bad. Now I only go with 4th/5th or back there.
Probably too much information, could have just said you're not missing shit.
