It seems to be for decades now, since concerts were daily business... Anyhow... I like to think about my last one. Cologne, 'The Growlers' form California, bunch of beers and a nice crowd! God, I miss these days...
My last concert was Halsey on the 5th of March and it was so amazing! But the best concert I've ever been to was of the Jonas Brothers on the 8th of February. I had standing tickets so I was there at 2pm (the doors opened at 7pm) but it was all worth it, I even touched them when they walked by!
My last was one Russian band - Княzz, this year. If we're talking about bands which give world tours - the last year I was at LP concert at my city, she had a Russian tour.
Was at a little concert bar that I goto from time to time. Vintage Steel(70's80's cover band) and YYZ RUsh tribute band. Will be going there in October to see Pretty Tied up(Guns n roses tribute band)
The last BIG concert I was at was Alice Cooper in Florida.
My last concert was "Mine" - she's a German singer (Electropop / Alternative...difficult to describe..) who isn't soooooo famous yet. If you want, take a look! >> https://www.youtube.com/watch?v=mMtWvyOhfrM
The last concert I saw was last November when I caught Pip Blom, a band from Amsterdam at a club up in San Francisco. Pip Blom was really good with lots of energy and a drummer who was one of the most energetic that I've seen. They played with a local band, Buzzed Lightbeer that was kind of fun.
I had a ticket to Juliana Hatfield for Jan 28 of this year before the pandemic hit but my wife changed our vacation plans and we flew out that day instead. I'm not that unhappy though because the vacation was amazing and worth missing a show for.
My last concert was Sabaton in Leipzig. It was really spontaneous because a friend of mine couldn't go, so I took her ticket. It was really good, I also liked Amaranthe, they were one of the two support bands. The other one was Apocalyptica, but I don't like them that much.
