Name that tune?

[Classical_N00b]

Hello,

I have searched high and low for the name of this song, which starts at 3:47 (I've set it to the time)

To me, it sounds like Bruckner, or Tchaikovsky (though mind you, I'm a total n00b, hence my username
But it's bugging me - it's such a lovely piece, I'd really like to identify it.  Would anyone know?

Thank you very much!

Sounds like Wagner
