I keep finding out about new Shiina Ringo releases until long after the fact -- like her last album Sandokushi, released last Spring. Haven't listened to it yet, and I hope it doesn't suck.
She also just released another compilation album, which sports a new duet with Hikaru Utada, "Roman to Soroban". It's jazzy with that Shiina Ringo pop sense, and it's fucking gold. These two voice couldn't be more different, and yet they always work so well together.
Check out the outstanding video for it here. My lizard brain just texted to say that Shiina -- at age 40 -- has never looked as tasty as she does in this video.
