Earth Wind & Fire '76 Think they were playing the Silverdome on the bicentennial, or at least the same week.
Led Zep '77
Pink Floyd '80...had tix lined up for night 4 of The Wall in NYC, but then our lodging (a friend's aunt and uncle) fell through.
Queen '82. Free ticket and I let it slide. #dumbass
The Smiths 1986
Husker Du, Warehouse tour ('87 or '88). They should've been playing a 2,000 seater, played a 700-capacity club instead.
Voivod, Nothingface tour, 1990. Soundgarden and Faith No More were the opening acts. Working midnights at the time; couldn't afford to take the night off.
The Waterboys, Room To Roam tour, 1990. Car broke down on the way to the gig.
Nightwish, 2004. Nearest show was in Toronto. Got myself a ticket for the August show, but the band couldn't get into Canada bc visa issues. They rescheduled for the weekend before Xmas, but too many commitments made me miss it. Still have that unused ticket.
U2, 360 tour. Toronto again, this time passport problems on my end. Still have that pair of unused tix.
There's more, but enough for now.
