Glad you like it! I'm the director, I arranged all of the music. I had two stereo rigs recording this. 1st rig (for the battery instruments) is in my sig, AT853>Tascam DR-100mkII. 2nd rig (for the pit instruments) is Rode NT5>Edirol UA-5>Zoom H2n. Both sets of mics were about 8 feet high. AT853's are locked about 15cm apart, and the NT5's were about 5 yards apart. And yes, they picked up on the mallet instruments almost too well, you can hear every mistake!
For fun, I took this and made my first surround mix out of this!
