for me many rock bands sound better live than in the studio. occasionally some bands put out great live albums which catch the moment and put all their studio stuff to shame. Im thinking of

if you want blood -AC/DC
Live at Budokan - Cheap Trick
What do you want from live - Tubes
Live at Fillmore East - Allman Bros

whaddya reckon?

I think metallica are well known for that, i think a lot of there songs are a bit flat on the records, but stuff like "one" comes alive Live!!
Id say guns n roses are better live too because they take some songs in different directions on stage, aerosmith do that too, big jamming sessions!

Iron Maiden are amazing live. Great tune, great stage preformence and speeded up songs.

PS. I think Maiden album songs are too damn slow, anyone agree?

I really love a good live band.
Bands Like Metallica do just come to life when they play live. The songs sound more "Full" if you undertsnd what I am trying to say. Another great live band is Pink Floyd...if you can try and check out the dvd/vid of their Pulse tour of 93 (I think ) it rocks.

maiden are awesome live, i can't wait to see them this summer
dream theater is great, especially when all the guys go nuts on their instruments

blind guardian are very very good live, the only thing that makes their studio studd better is the fact that they put in many layers and nuances that make the songs better

iced earth is great live as well

After three years of playing I tried to play everything as fast as possible and that sounded, I would say, like ****, and I didn't realize that if I'd play bit slower things than I was capable of playing then everything would sound much better.

Grateful Dead, Phish, Jimi Hendrix, String Cheese Incident, Allman Brothers, basically anyone who improvises...

sounds better live than studio.

ive always thought that yngwie malmsteen was awsome live..i like it beeter than the pre recording..for some reasn his improvisations sound better than the orignial solo itself
