Getting popular in Europe, but I don't know many people in the USA familiar with them. The Baseballs are entirely a cover-band from Germany. If you're a fan of the '50s era I think you might take an interest in these guys. They got that garage rock, doo-wop feel and image. I've listened to the album "Strike!" at least a dozen times by now, and my favorite cover is probably the Leona Lewis one, YouTube - The Baseballs - Bleeding Love Not an official video, but you can find there's from that.
