"Guilherme Efe is a self-taught guitar player from Leiria. (...) using his own experience as a guitar player, he has created an unusual and rigorous new project called Grutera that lives through a single guitar (nylon and bass strings). His sound can be compared to some other contemporary artists such as Filho da Mãe or even Norberto Lobo."
"Sur Lie" is his third album, released in November 2015.
