Episode 8 - what is this song?

Hello,

can anyone tell me the artist and title of the song that is played in episode 8  00:42:33-00:44:52? I fell in love with it instantly but can't seem to find it anywhere. 

I'm a huge music lover and this is going to bug me for a really long time. I'd really appreciate your help! :)
