[Tango-L] Translation of Lunfardia lyrics

[tanguerochino@netscape.net]

I am working on a translation of the lyrics of Lunfardia, sung by 
Adriano Celentano. I've done most of it, but would like help with the 
following lines. 
 
en sus pasos el tango 
en la bocha un clavo pa’ doblar 
 
- In her steps the tango 
- In her head ...?? 
 
por cada escarcha que cae 
una rosa abierta ella cultiva 
hasta que le escupen polvo de oro 
que en el profundo centro de su deseo cruel arriba 
 
- For each frost that kills 
- a blooming rose that she cultivates 
- until it shoots out gold dust 
- ....?? 
 
Thanks in advance 
 
TC
