Here's my request.
They are both from the anime Uragiri wa Boku Namae wo Shitteiru (aka Uraboku) or Betrayal Knows my Name.

Song: Past and Sadness (http://www.youtube.com/watch?v=jV3of8By4Y4)
Artist: Shougo Kaida [ Shōgo Kaida - according to Wikipedia ]

As far as I know, I can only find one song from this anime and that itself is found in this very forum as well. I hope to hear from you guys soon.

Transcribing "a lament" for piano.

As far as I know, there are more than one of the soundtracks from uraboku were transcribed by me and are available on my website. :P http://sperion.web.fc2.com/

Done "a lament" apart from the first section.
pdf and midi can be found at http://sperion.web.fc2.com/

Ah, thank you so much!
