In addition to Adelita, this song is also by Francisco Tárrega. For a little insight into this song, he was from Spain and, in Spanish, lágrima means tear (as in from crying). 

When I recorded this, it was during summer when cicadas were in their prime outside. I generally like cicadas, however, I learned their noise is not ideal when recording classical guitar. In fact, they end up making a faint cameo on the recording. Since they are rather faint though, I don’t especially mind, and can in some ways appreciate this artifact that reminds me of the experience recording this.
