Teen Gothic

I've absolutely fallen head over heels in love with the song, especially the last 3 minutes which are just staggeringly beautiful. Does anybody have any recommendations?

I know it had a Pink Floyd influence but besides that I was thinking any other bands and even artists. I have come across some bands that sounded close enough like Lycia (Well kind of). I would say it doesn't have to be goth but that would probably break the second rule.
