As a huge ARIA fan I was surprised and saddened last year to hear the news of Eri Kawai's death. I still don't know much about it but I'm fairly sure she was very young, and it really came out of nowhere. As I was browsing Anime News Network I saw that Victor Entertainment has released
a memorial album featuring her songs..

It was sad news when, just before noon on August 4, 2008, singer-songwriter Eri Kawai passed away. She contributed songs to Aria the Animation, Air and Tales of Symphonia, among others. A memorial tribute album, Himawari (Sunflower), was released on December 24, 2008. The album features songs from Aria, Bamboo Blade and Sketchbook ~full color'S~. Four live tracks from ARIA The CONCERT, which were never intended to be released to the public, complete the present to Kawai's fans. "

I would love to hear these live tracks, myself. I didn't know they had an ARIA concert
