I went to the show in AC. It was good overall. There were high points and low points but the high points outweighed the low points. Brent does a soapbox type rant. He knows his stuff but his visual was terrible. It will become obvious to you that Manson is in fact Ned. Pay attention to the style of dancing between the two; the moves are exactly the same.
Detroit certainly has its problems, but not all of it is a blighted wasteland - just most of it. The area around the Fillmore isn't too bad. If you want to have a real Detroit experience, go to Harpos!
