#8, it stands out in a nice way. I wonder if you can do something with the "C" on top to get more color - maybe with the colors of a globe (blue and green, and maybe some grey?). Just making suggestions. I like the way the C sits on top of it, but the C needs to stand out more (in my opinion).
I hope you would like the changes, now the C stands out more and I think this combination of colors is good for this design, if you want other changes please tell me and I will provide :)
#35 - is there a way to make it look a little less "clean" - it almost looks like the logo for a charity or non-profit (which is cool, but not exactly what I'm looking for).
Maybe the globe could be an old record / phonograph? Or something that feels more old school.
I'm still brainstorming I just want to see it feel a little more like the vibe of the music - if that makes sense.
I created for you some new old school and vintage designs that I hope you would like. I counseil you to avoid symbols and think about a type logo, a unique and original word logo that make your band easily recognizable. If you want other changes please tell me.
