Last night A Perfect Circle dropped by the Last Call with Carson Daly studio and put in a performance of their track "Weak And Powerless". Taken from their album Thirteenth Step it's the second time the band have visited Carson in 2 months. Someone is a big fan of A Perfect Circle, I think! Check it out up top and if you want to pick up their album Thirteenth Step you can do so over here. Thanks to The Audio Perv for the video.
