This is an excellent DVD.  It basically consists of Bono and Daniel Lanois going through the old master tapes and playing with the knobs and controls to hear things recorded that didn't make the final cut.  This in turn  brings back memories to them of what was going at at that time.  Also has  The Edge playing with home demos, some live stuff, and the video for  Sweetest Thing.  A very cool video that I only wish was longer.
