Very excellent, high-energy piece. I was surprised to see so many reviews citing the beginning as the weakest part, because I thought it was a wonderfully strange introduction. The introduction of subtler layers of percussion on top of the basic drum & bass helped make it more exciting. The soloing that started at 1:17 was top-notch. The one weakness I felt the song had was the use of string synth for the lead in most of the piece, which I didn't think had a very good sound, at least by itself--it was better in a support role.
It's a very tightly put-together song, though, and sounds really good on the whole.
