I’ve seen Pentatonix three times. They are all very young.
I’ve seen John Mayer but would like to see him again. I love his latest album. He can really play that guitar.
I would probably enjoy Gaga as well, though I don’t know her body of work as well as the rest of my favorites.
An oldie I haven’t seen but would love to is Eric Clapton.
I’ve thought of one! Vampire Weekend. I have never seen them in concert, and I would love to. Maybe a little bit less now that Rostam Batmanglij has parted ways with them, but I still think they would be fun.
Seen Vampire Weekend and Jack White. Both are very good live.
I’d like to see Red Hot Chili Peppers live. I here they put on a great show. Wishing I was at Bonnaroo this year but decided to skip it this year. Weather looks perfect.
We saw a fair number of concerts with our son - a lot of Finnish music mostly metal-ish. If you want a fun concert I highly recommend Apocolyptica - they started off by covering Metallica on cellos, but they play a lot of their own music now. They went to conservatory in Finland, but then decided playing rock music was more fun. Lincoln Park puts on a good show - we saw their last tour. The new album is kind of folksy, not sure what sort of a show it will be.
If we’re recommending touring groups, I’d like to put in a plug for The Tedeschi Trucks Band. Derek Trucks played with the Allman Brothers and is probably the best slide guitarist on the scene today. His wife, Susan Tedeschi, is a grammy winning artist and has a voice reminiscent of Bonnie Raitt. Together, they play fierce originals and covers of classic rock and blues.
Have seen them three times and they play their heart out every show: https://m.youtube.com/watch?v=h0kXfPrHHcw
@garland , I have seen Brandi Carlile several times … SO GOOD!!
@CottonTales , I saw Jackson Brown years ago. He was really good live.
I saw many, many bands back in the day … the one “big” rock band I never saw was the Stones. I wouldn’t want to see them now, but I really wish I had seen them when they were in their prime.
I saw the Rolling Stones four times, two of them on their 1975 tour, which was the first after Ron Wood replaced Mick Taylor. I don’t know if I would call that their “prime” – unfortunately, for the Stones their musical prime more or less coincided with their functional nadir – but it was pretty close. I saw one concert from the second row in a venue with acoustics so awful it was sometimes difficult to tell what they were playing, and another concert with exactly the same set list from the furthest edge of a stadium where I could barely make out the band, but the sound was perfect (if slightly delayed relative to what one saw onstage). Anyway, it was fun to see Mick Jagger cavort, and his energy was impressive, but musically it didn’t do much more than represent a somewhat shambolic recreation of their recordings. When I saw them again about a decade later and about a decade after that, I didn’t expect more, and didn’t get more, although Keith Richards seemed less impaired than he had in 1975.
I would love to see them covering blues songs in a theater or large club (or small club, for that matter). But you can’t always get what you want . . .
@JHS YES! Vampire Weekend is my jam!
I also love Sufjan Stevens and I’ve seen him twice. Unfortunately, I think I like his studio work better than his live performances.
Edited to add: I almost forgot the Lumineers. Another group I’d love to see.
I saw the Grateful Dead about 20 times back in the good old days—they were magical. (Or maybe it was the mushrooms that were magical at the time.) Still, after watching the remnants on pay-per-view two years ago when they were in Chicago, I think sometimes you can’t recreate what was.
@EllieMom Lumineers are great live - lots of energy (much more so than Sufjan Stevens IMO).
The Lumineers are opening the U2 concert I’m seeing in a couple weeks–Bonus!
Side benefit of U2 --I’ve seen many newer (at the time, at least) acts opening for them–PJ Harvey, Garbage, Kings of Leon, Interpol, Muse, among others.
Muse AND U2?! What a show! I saw U2 with Black Eyed Peas a few years ago. Wish I could have a do-over!
That was pretty great! I wouldn’t mind seeing Black Eyed Peas either. On one tour, I saw some group I’d never heard of, Stereophonic, like three times. Never warmed to them–just sort of blah. (full disclosure, didn’t love Kings of Leon either.)
@audiophile Can I assume you are a Warren Haynes/Govt Mule fan? Love Susan Tedeschi 
@NEPatsGirl Absolutely!
@garland Saw Sterephonics open for David Bowie at a local performing arts center. They were so loud, my ears were ringing by the time Bowie came on (he was great, of course!)
I’d like to see U2. We are going to see Hall & Oates with Tears For Fears this month at verizon center in DC.
I saw Paul Simon Friday night. Went to a party yesterday where others had also seen him. We all agreed he was not at his best/seems to be losing his voice. He is 75, so not surprising.
A couple of years ago, Paul Simon performed at a local library. His voice was not what it had been and it may never be again, but geesh, I was 20’ away from PAUL SIMON! That was so much better than even the Central Park concert that I attended in the 80’s.
I’d like to see Alabama Shakes. I’d also kind of like to see Buckethead.
I’m happy I got to see Johnny Cash, B.B. King and David Bowie before it was too late. Linda Ronstadt, too, although she was disappointing in concert, honestly (she’s still alive, but doesn’t sing any longer). Saw the Eagles so long ago that Fleetwood Mac was the opening act.
@Hunt Alabama Shakes is great live. I’ve seen them a couple times and will be seeing them again in August. Do go if they perform near you!
