Query: worst music dvd ever

Music does not sync with the rotten out of focus video shot behind people's heads. Terrible video probably even for its time. You would have to be a tripping Dead Head to even start to watch this. I love music videos but this is the worst I have ever scene, included CD is of poor quality as well though it looks a work of art compared to the DVD.
