Biography
Quaterna Réquiem is a Brazilian progressive rock band about which not much is very widely known. Their sound is symphonic, with presence of many keyboards, as it seems that the leader of the band is a keyboardist.
Their album "Velha Gravura" is an illustration of that and, in some places, it has similarities to Camel's "The Snow Goose".
