Opening acts create regrets, don’t they? I went to a good amount of rock concerts over the years, and I always, always arrived in time to see the opening act, even though I rarely cared about them. What’s interesting in retrospect is the moments where I should have been more dialed in, and realized what a treat I had seen (Tommy Conwell notwithstanding, although I did buy his first two albums).

For exampe: I saw Sonic Youth and Social Distortion open up for Neil Young in 1990 or 1991 before I knew who either band was. Sonic Youth! Supporting “Goo!” But I thought their set was meh, a wall of guitar noise but not my thing. Sigh. Social Distortion had some catchier tunes (one was on the radio at the time), so I didn’t mind them, and it did have the effect of keeping them in my brain for many years after, so I guess that’s something. Neil Young was good that night which redeemed me a little bit—I believe this was the “Ragged Glory” tour, with Crazy Horse, so the wall of guitar noise just kept on coming.

I went to the H.O.R.D.E. Festival in the summer of 1992, to see Blues Traveler (good call) and the Spin Doctors (guilty as charged). We spent the day and saw all five acts. The middle band was Phish, in their trampolines-on-stage period, which was fine enough, and if I’d paid more attention or smoked pot maybe I’d have caught a 30-year wave, but instead I still listen to “But Anyway” and not the Phish station on Sirius XM.

There were plenty of bands that didn’t matter, of course. Good old Tommy Conwell, for example. Forgotten names like My Sister’s Machine, who opened up for King’s X one time (and whom we ran into at a rest stop on the way home). And some marginally interesting moments, like seeing Angelfish, who opened up for (I think) Live, then broke up, leaving Shirley Manson free to join Garbage, and me free to say I saw her in concert before she was famous; and the lucky ones I actually dialed into and enjoyed, like Living Colour at Shea, opening for the Rolling Stones.

But then, in 2013, I went to a Justin Timberlake concert, and the Weeknd opened, in support of his debut album. We knew at the time that he must have been talented to get picked for that slot, but we thought he sucked. Shows what I know.
