"Cuban-American pianist/composer David Virelles continues the exploration of Afro-Cuban musical traditions begun with his first recorded collaboration with vocalist/percussionist Roman Diaz on Continuum (Pi Recordings, 2012), continuing through Mbókò (ECM, 2013) and Antenna (ECM, 2016). He uses "gnosis" to refer to ancient collective knowledge, and this music is about the intersection of cultures - contemporary improvisational language and Cuban sources, especially the sacred Abakuá percussion ensemble ... There are over a dozen instrumentalists and vocalists employed, but they are mostly broken up into various small ensembles: the concert premiere was billed as "futuristic Afro-Cuban chamber music" ... Yet the entire program maintains a consistent tone, simultaneously ancient and contemporary: a ritual for the modern world".
