This Blu-ray is filled with passionate performances and good rock from superstars U2.  Most of it is filmed in black and white for special effects, but it is none the less interesting and moving.  It goes back to the 80's right after the Joshua Tree CD and gives a glimpse of what U2 was about back then.  Bono provides a moving explanation of what Sunday Bloody Sunday is about that you may not find elsewhere if you are a U2 fan.  There is a strong deep bass track through the performances which sounds good on my subwoofer.  At a couple of points I could hear the bass amp speakers go into distortion close to blowing a speaker and also some bass feedback distortion like Jimi Hendrix, although I think this was unintentional for the song and accidentally made its way into a highly revealing master audio soundtrack.  Since it has dialog interspersed with the music, I don't listen to it as much as if it were a pure live performance, but it is a good insight to U2 as a band and as individuals and it is worth it for that.
