Momiji reminded me of another of my favourite Japanese acts: ROUND TABLE (featuring Nino).They only have 2 full albums with Nino though, wish they'd put more out.

Momiji will likely recognize them from "Let Me Be With You," the opening theme to Chobits. More recently, they've performed the opening song "Groovin' Magic" for Gunbuster 2, "Puzzle" for Welcome to the NHK, and a brand new song for 'Clamp in Wonderland' (along with Maaya Sakamoto). Their music makes me want to dance.
