They do have a new singer, that does alot better job.
I was at that Sector 7G show, and honestly, every band but all time low sounded awful. Their sound person that night wasn't at the boards most of the show, and the mixes on pretty much everyone were bad.
I was pretty upset, cause if you watching bands play awesome shows you don't want them to sound bad because of the audience mix.
I think all time low got the shittiest end of the stick that night you couldn't hear guitar at all. Just bass and drums
