This has a ton of professional sounding instruments and effects! This is definitely one of your most outstanding pieces for sure. This even beats Man on the Run. Dude, this is so good I'm gonna try another of my long reviews :). You better respond >:o
First of, the kick. It just sounds amazing with the mix. Sounds perfect for a trance piece. I'm lovin' it. Can't say much more about it. It's awesome.
The clap, well, there's a bit too much reverb on it imo, because every 3 claps there's a 2 clap change in beat (I hope you know what I mean, hard to explain O_o) and the 2 odd claps have less reverb on them, which makes it sound a bit weird.
The hat is alright, fits with the mix and doesn't wear out unless your listening to it only. Not much to say here.
The blips that go throughout are amazing. They just give that trancey feel that would have been much less without them.
The baseline that becomes apparent at 1:02 is very trancey as well. How did you make that? Is it an arp? Meh, sounds good.
The main arp's lead sounds great with the other instruments going on. The sound also fits nicely with the melody and vocals.
Enough of instruments, time for the parts :)
The intro is dead-on. BAM straight in your face; some professional sounding trance. Sounds great. The half-gated synth there had an amazing effect on the rest of the mix and filled the empty gap that would've been there.
The intro of the vocals is just great. The fade-in was great. Gave the vocals some depth and variety.
2:17 was superb. The pad sounds spectacular. The little melody with the soft lead at 2:17 also sounded like it had potential, too bad we didn't get to hear more of it.
The outro, well, I guess it could have been better, but everything else can compensate for that :).
Well, that's the end of another attempt at a long review :S. Hope you enjoy this review and stuff. Great work here, love to see more work from you like this. Good luck :)
