I agree w/ ~Matt~. fra foa is/was a great band and Chisako Mikami pretty good as a solo artist as well. I just bought her "Here" album and I really liked it. I haven't heard her first solo album though. "13 Leaves" by fra foa is great CD too.
fra foa songs:
Light of sorrow
Mahiru no Himitsu/真昼の秘密

Aoijiroi Tsuki/青白い月

Kirameyuku mono/煌め逝くもの
Chiisana Hikari/小さなひかり。
Kienai Yoru ni/消えない夜に

lily
afterglow
Sumiwataru sora, sono mukou ni boku ga mita mono/澄み渡る空,その向こうに僕が見たもの。
Mikami Chisako songs:
Here

Yes
Soutaikei/相対形

3set

Saikidou/再起動
Chisako's songs are really unique and aren't for everyone but I listen to her CD all the time. Her voice is very "raw"^^
I also listen to Nightmare and Shaka Labbits. Shaka Labbits is kinda punk or ska or whatever you call it.
Does LOVE PSYCHEDELICO count as rock?
I'll upload some stuff by all of them if you'd like.
