We saw the Pink Floyd tribute band "Bricks in the Wall" last night at Antone's. I love tribute bands and I put this one very, very close to the top of the list of my all time favorites. Go see them if you ever have the chance.
Instrumentally, these guys were amazing. They kicked Pink Floyd tribute band ass. However, while the vocals were fantastic (including two amazing female backup singers) the male vocals didn't really sound enough like the vocals of the original Pink Floyd for me to bounce these guys to the absolute top of my favorite tribute band list. (The top spot is still held by Hells Bells, an amazing AC/DC tribute band.) I'm not saying that the vocals weren't good. They were great. To my ear, they just didn't sound very much like the original Pink Floyd.
I give them a 4.99999999 out of 5 on my tribute band scorecard.
