it symbolizes dj head with headphone and also an equalizer on dj's head. in other look, a subwoofer with colorful sound particules equalizer. You can use it an dynamic equalizer animation which is making adobe flash professional. it can easily use different channels like media, t-shirt, boards, tickets, web, graphic design works.
I like 3 and 8 the best right now. The equalizer bars don't feel quite right yet from a color perspective and I'm not sure it has the personality/excitement i'm looking for.
for #14 the yellow techno raver words hurt my eyes or seem a little blurry on a white background. I like the new crisp waves with the light on them on the left and right sides of the logos. I like #15 alot but the black bars at the top turn me off, but i think you left those in by accident after switching from the black background.
#51 doesn't feel right to me, although i like that it's abstract. #52 is a speakerbox but i'd like the icon to be abstract enough where the only name someone could use for it is "charlotte techno ravers logo"
#52 is not speakerbox, it's your release logo:) today, i watched q-dace videos on youtube. and i made #52, i think, you dont need a story teller logo, you just only want to a symbol, like q-dance, because of this i try to see which logo can use these concert hall, or huge techno parties.
