Your disclaimer. As we've said before, disclaimers are usually ineffective (and yours has a few problems). Even if you're not claiming rights in the underlying song, you are probably claiming rights in the copyrighted sound recording and video. That is, if somebody began making money reproducing your video without your permission, we assume you would pursue them. Also, claiming that the video is "informational" is confusing. Typically, such a claim is to distinguish it from being commercial and we don't think that's the case. Self-promotion is typically a commercial endeavor. We think you can ditch the disclaimer.
P.S. All bands are inconsequential in the larger scheme of things
