Just a short review:
The gig took place in a musical theater, were normally The Phantom At the Opera is performed. So all family was well seated in row 12.
The Machine begun with Wish You Were Here, the complete album!. Then they announced a little break telling us, that after the break they will play the complete The Wall! And so they did! (they played net nearly 3 hours)
The performance was not a 100% copy of the original PF (let's say 95 %), which gave it a little personal "Machine" note. As an example, the speed of Shine on You Crazy diamonds was much slower than the original. Also the did a little jamming where the pieces allowed. Performing the wall I remembered very well the original PF gig I attended here in Dortmund. Of course, the 4 ppl (plus one saxo from time to time) could not give all the volume that the min 20 musician gig of the original, but is was really astonishing, how good they were. Chicken skin many times...

. Also they used the original of PF projected to a round screen like at the original.
After heavy applause from the sold out audience, they played Money, which they used again to jam..
Different to Musical Box (which I saw together with RogorMortis) was, that they were not glued to the original and I felt (just my personal impression) that they played it with heart and 100% dedication, having fun doing what they were doing.
So, if this group appears near to you, don't miss it. My daughter, my son, Doris and me had a excellent time.
