For sheer spectacle, I'm completely sold on any live show from Muse. The production values are top notch, there's plenty of theatrics, and Matt Bellamy can hit every single one of those notes, time and time again. I've never been a huge fan of the band itself, but they sit atop my better half's list of favourites, and I'm glad she's taken me to two shows. This year's tour was awesome, but I'd avoid any of the amateur recordings on YouTube right now as they can't accurately capture it IMO.
When I think of my favourite live performances, it really depends on the band and location. I saw Radiohead in Chicago at Lollapalooza in 2008, and it was mesmerizing. It was a huge festival venue, which I thought would detract (especially as they weren't co-headlining that night with another artist on the other side of the park), but it didn't. The band knows how to toe the line between following what people hear on albums, and reimagining just enough to make it memorable. Also, In Rainbows had just come out, and I was blown away by it, which helped. The atmosphere, with everybody just absorbed by the performance, or thousands singing along, was perfect.
On the other end of the spectrum, I once saw Death From Above 1979 in a tiny little basement setting. The ceiling was low, everyone was sweaty, and it was a few years before they released their second album, so the show was almost entirely based around the debut album (which remains one of my favourites to this day). It was the perfect venue for that sort of music. This is obviously very different, but I still love this old clip of them on Conan, when Max Weinberg jumps on the drums and utterly kills it (I feel like
@ImaRobot will appreciate):
Then there's LCD Soundsystem. My favourite band announced it was breaking up a few years ago, and I missed the Toronto leg of that final tour. Then the movie on the very last show at MSG came out:
The movie captures a feeling so clearly. It also introduced me to a version of my favourite song that was somehow, almost impossibly, improved upon. The live album for this came out a few years later, clocking in at over three hours. Then there was the news of the band's return. Sam picked up tickets as a surprise for me, and finally seeing the band live, even here in Toronto, was great. In a weird way, the whole breakup rigmarole doesn't matter to me: it feels oddly appropriate for a band like LCD.
