Listened to the first song. Cool stuff. Couple of ideas:
-get drummer to lay off the crash. It doesn't let the guitars articulate as well, and with the quality you were stuck with I couldn't hear the chorus at all.
-if your bassist was trying to slap in there, he NEEDS better tone. If he wasn't, well then he NEEDS better tone.
-get a slightly less chunky and more cutting-through guitar sound. That way when you start playing chords they don't turn into a wash of sound.
You're material itself was good stuff for that song, a couple of riffs I liked a lot. Think the song should have had a bit more variety though. Still, for a demo, that was well done.
