I searched for ages when I younger for TMTATS, and only recently have I found it in the stores haha. It was out of print for a while iirc right? Or something like that.
Brand New's 'Southside Festival' Bootleg/Soundboard is awesome too. Great sound quality.
Live albums are good in some ways; giving you a chance to experience the show, but at the same time you still feel a bit removed from the atmosphere, which is a given really, seeing as you aren't there. They are a good substitute for not going to a show, although it can be bittersweet, listening to a great show and acknowledging that, but at the same time you wished you could/should of went.
It's a tricky one, I'd say it's usually never as good as actually being there; atmosphere makes a huge difference... it might be enjoyable to listen to but when you're listening you can't help but feel you're settling for second best.
I don't really like live albums, unless I happened to be at the show it was recorded, like the Starting Line's final show in Philadelphia on April 18, 2008. I like being able to connect a memory to what I'm hearing, and if I can't do that, it just loses its luster.
Live albums are never an essential listen for me. If it's somebody I really like, then I'll buy them, but 99% of the time I prefer the studio versions of the songs. That said, here are some of my favourite live albums;
The Who - Live At Leeds
MC5 - Back In The USA
James Brow - Live At the Apollo, 1962
Sam Cooke - Live At the Harlem Square Club
Bob Dylan - I like a lot of the many Bootleg Series that he's put out, I'll go for number 4 as my favourite overall
Bruce Springsteen - Live 1975 - 85
And more recent ones:
Green Day - Bullet In A Bible
Thrice - Live At The House Of Blues
Tegan and Sara - Get Along
NOFX - I Heard They Suck Live / They've Gotten Even Worse Live!
Bad Religion - 30 Years Live
The Bob Dylan bootlegs could be ranked completely separately. Heh.
You know, I don't think I ever heard that Green Day one. Weird. I remember it coming out - and I just ignored it I guess.
