The fabric on the front side walls are not decorations.  They're acoustic panels.  The cherry wood on the side walls are angled at precisely 7.5 degrees so that sound will not reflected back to the same spot twice.   The walls are two layered, with the outer wall not touching the inner wall.  

Everything you see here is not randomly done, everything is measured acoustically, precisely, and carefully.

The only thing I regret is that I didnt have my Tripod with me so the pictures didn't turn out too nice.   I'm going back.......
