I really wonder what Sandpiper is going to sound like. I hope it's a folkish song like Hikari no Senritsu. I hope that there is going to be at least one folkish song on the album because they really do incredible magic with those. I also want songs like Ongaku, love come down and progressive, but I'm honestly open to anything new sounding and I think this album is going to be quite different from their previous ones.
EDIT:
Heare are even bigger versions of the covers + album related twitter pic and one from official site
btw. is it just me or does Keiko look like alan a lot on the type b mousepad pic?
