This is a super beautiful piece and, surprisingly, not too difficult to learn (at least at a very basic/simple level). That said, tto execute it properly and with the right dynamics is still very much beyond my current skill level.
Here it is, with lots of finger noise and some messed-up notes 
One of my favorites interpretations of this song is this version by Paola Hermosín, which also includes an interesting bit of story about Tarrega and the said passing of his toddler daughter some time before Lagrima was composed.
