The band is called A-frica (아프리카 in Korean), and they immediately remind me of good old eighties hard rock. The live performance I'm going to post below really stuck a chord with me because their vocalist is so exceptionally talented.
Got any info? Please shoot me an e-mail or leave a comment on this post. I don't care how you do it just as long as we shed some light on this group. Even if nothing comes out of this, at least I've exposed them to more people.
