yeaaahhh I just now looked at the price of the 24-70mm >.< *sigh* maybe someday. Man I hate how expensive photography is. Oh well i'd prefer a zoom lens, but I'm probably going to go with the 50
What about the 50mm 1.4? It's reviews says that the color is better?
I love my 50mm f/1.4
I'm sorry, I'm exhausted trying to get ready to fly out tomorrow, so I missed whether or not you shoot Canon or Nikon (I saw both mentioned in this thread), but I'm a Canon shooter with a 50mm f/1.4.
I actually shoot with a T2i, which is obviously the model before yours, and this is my go-to for concert shots.
Well... to be fair, it's my go-to for pretty much everything since my lens selection is limited at the moment, haha, but the reason I *bought* it was for shooting live bands.
You can see some of the stuff I've gotten with it in my Flickr stream (which is linked in my sig).
I agree with everyone saying that if you're shooting in small clubs you don't want a long lens. Sometimes the 50mm is almost *too* long... so I got a 28mm.
I use the 50 when I have a little room to backup without anyone's heads getting caught in the shot or when I'm pressed up against the stage and what a "headshot" kind of deal of one of the musicians.
I use the 28mm when I'm pressed up against the stage and want more than just their eyes and nose in the frame

Okay, that's a bit of an exaggeration, but my point is, unless you can get back *and* higher (as in above everyone else's heads), the 50 is pretty much as long as *I'd* wanna go in a small club setting.
Opinions may vary on that.
And I love having the f/1.4 vs. a f/1.8, because that extra stop gives me some wiggle room.
Lenses aren't at their sharpest at the most extreme ends of their aperture capabilities, so having the f/1.4 allows me to shoot at f/1.8 and it'll be a bit sharper than the 50mm f/1.8 at f/1.8 will be.
That being said... sometimes venues are just *too* dark and I *need* to shoot wide open... which is again, where that f/1.4 comes in handy because it gives me an extra stop of light for those venues whose lighting guys were out to lunch during the gig.
I honestly try to shoot around f/2.8 if possible, but I usually have to adjust from that aperture depending on the venue and lighting.
I don't know if ANY of this was relevant to what you're asking, but I hope I helped *somewhat*.
