They Chose this Name as a Contradiction and Logically Because They were in the Process of Creating the Album with Effective Pop Songs and "Efimera" Or "EPHIMERAL" Only Endures for a Short Time. Produced by Carlos Jean Together with the Spanish Duo, Arquitectura Efimera Counts on 12 Songs Based on Guitars and Electronica - the Purest Fangoria Style but with Grand Artistic Construction.
