Saber, Querer, Osar y Callar (Spanish for To Know, Want, Dare, and To Be Silent) is the twenty-first studio album by Omar Rodríguez-López as a solo artist.

"Tentáculos" is an alternate version of "Agua Dulce de Pulpo" from Rodríguez-López's 2010 album Un Escorpión Perfumado. This version was performed by Omar Rodriguez-Lopez Group during 2011-2012 live shows.

Several more of these songs resurfaced in the 2016 Ipecac series on the record Zapopan as alternate recordings. "Spellbound" & "Tentáculos" then also appeared on the 2017 live album Chocolate Tumor Hormone Parade from performances in 2012 by ORLG.

All songs written, arranged and directed by Omar Rodríguez-López, except where noted.
