Colors are a matter of taste. But I don't find them very comfortable to look at, too.
+ it's not much of a blog, though, yes. You may have just started it, but it already has too much content listed with no apparent information. I doubt any of the releases mentioned will make anyone think "Hey, I gotta check out that artist!"
So you could arrange stuff clearer. Write something that makes the reader think "I have to listen to this!"
But that's not the first thing you should do.
First, you should definitely have an idea of what you're doing there. I don't mean to be rude by saying that. I mean, if you want to have someone read or see your blog + the stuff on it, you'll need to start with a plan.
Briefly speaking:
1. Plan.
2. Blog.
3.???
4. Profit!
To me it appears like priorities 1 + 2 for you are just the other way around.
