Mestizo Quail

[munkinhead]

Mariachis bend and trail,
guitar whispers a sad tale,
concertina halts its wail,
run to ground, and back to jail.

Not much meat to chew on here, and it ends all ends in -ail. It would be good to know what this is about. Why do Mariachis 'trail'? Why are the (Mariachis?) put in jail?
If you wanted to make this longer though, you might have to change the way you're rhyming, or you'll quickly run out of words to end lines with.

Sounds like a border song.
Narcotraficantes.

[munkinhead]

Human trafficing actually.

Please give us some more clues next time, or add more here. We'll be able to appreciate the whole thing better then. :)
