Mmmm...
To kill a mocking bird is actually a pretty good book :-)
Now, this review may sound negative, but it's not suppose to be. I only take my time to review songs, if I see some potential or if they are good. Both apply here :D
Besides, reviews like OMG THIS IZZ SO KEWLLL never helped me.
OK.
The song itself: Nothing really to say here, the buildup was cool, I always enjoy some sampled speeches / quotes etc. Very metalcore.
The guitar:
Your playing was great, the style was cool. BUT i did hear some parts out of tune, is that what you meant with 'flat'? The part starting at 6:32, you can hear that the two rhythm guitars panned left/right don't fit. But it's just slightly out of tune, no 'biggie'. Just remember to tune your guitar during recording ALL of the time. Best is to always have a tuning device connected and constantly checking. The tone of the guitar was ... ok. I'm guessing you're going directly line-in, and not recording via a mic and amp. The sound is very fuzzy, it has that typical line-in distortion sound. I also record that way, i use a noisegate, then a distortion pedal, and then go directly into my audio interface. But i found a great trick to get rid of that 'fake' distortion sound: impulse loaders. PM me if you want to learn more about em :D I'd be glad to help.
The Vocals:
The quality of the recording was good, the volume should be lowered just a tad. Also, the vocals do not really blend into the mix, simple solution: add some reverb. but not too much. The vocal performance, was ok, i certainly know what kind of style you're aiming at. The problem is, you're not using the full potential of your voice. There has to be more fry in your voice, the beginning of each 'shout' is clean only at the end it turns into a real 'scream', if you know what i mean... :D Just try it all LOUDER.
The bass blended in pretty well, i like it when the bass has a little more presence, but that's just a personal opinion.
The drums also sound quite ok, the bassdrum did a good job. haha
The snare sounds a little trashy, like an empty can or something, but it's ok. The symbols sounded a little trashy at times, but meh!
Overal 9/10, 5ed.
I know what it's like to dig up old songs and try to make the best of em.. it's a bitch!
:D
