Silencio is the name of two musical artists. Firstly, an instrumental math rock/prog rock band from Ohio, who released an album named "Dead Kings" in 2004. The other, is as follows:

"More than anything else, Silencio is an ambient music project.
Created by jul (Eglantine Records) in 2001, this project started out
rooted in lo-fi electronics and sound collage, creating dark and
uncanny atmospheres. These experiments gave birth to "Sehnsucht",
Silencio's first album, which was released on French label Grand Téton
in june 2004.

By the time this raw, personal and uncompromising record was released,
Silencio turned into a two-man project as Nicolas Lecocq joined in.
From then on, both members decided to explore new sounds in ambient
music, and turned towards melodies which Sehnsucht was almost
completely devoid of. New compositions, some of which were conceived
for a mini tour in Europe (through Belgium, the Netherlands, Germany
and Denmark) brought piano and guitar melodies forward, considerably
lighting the band's sound. Further work was done in that direction,
and quickly gave birth to their new album Grünezeit. This peaceful and
contemplative collection is both the fruit of a strong friendship and
an ode to daydreaming.

Grünezeit was released this fall on Belgian label Carte Postale
Records, right after the duo embarked on a second mini tour to promote
their new work along with labelmate Jumbo Jet."
