@Soap Music : I don't know why your Yamaha dealer would have any of their CD's but they're available online. If you buy from Tower Records Japan, you can get internationally shipped: https://tower.jp/artist/2140097/MONSTER%E5%A4%A7%E9%99%B8
Amazon seems to have some, too, but they're heavily marked up. I think it's awesome that you're willing to support these guys.
