Is there some question about the legitimacy? There are a few, very brief snippets out there on Youtube type video excerpts. To my ears, the playing from his young Berlin based musicians sounds pretty darn good. One excerpt is from the finale, right before the solo bass drum makes its reappearance after the high strings have taken up the "flute melody". What's kind of weird though, is that Gamzou adds a big bass drum roll shortly before the return of the solo bass drum strokes - best to let that solo bass drum stroke sound stark as possible, don't you think? In other words, don't prepare it.
